How a Flashlight Work?

1 - Case The tube that homes the elements of the torch, as well as the batteries and lamp (light bulb).

2 - Contacts a really skinny spring or strip of metal (usually copper or brass) that's set throughout the torch, creating the electrical affiliation between the assorted elements – the batteries, the lamp, and also the switch. These elements conduct electricity and "hook everything up," finishing the circuit.

3 - Switch The flow of the electricity is activated after you push the switch into the ON position, providing you with lightweight. The flow of electricity is broken once the switch is pushed into the OFF position, therefore turning off the sunshine.

4 - Reflector A plastic half, coated with a shiny metallic element layer that rests round the lamp (light bulb) and redirects the sunshine rays from the lamp to permit a gradual ray, that is that the lightweight you see emitting from the torch.

5 - Lamp the sunshine supply in a very torch. In most flashlights, the lamp is either a W filament (incandescent bulb) or a light-weight emitting diode (solid state bulb), additionally called associate degree crystal rectifier. The W filament or crystal rectifier glows once electricity flows through it, therefore manufacturing actinic ray. W|metal} may be a natural element and also the W filament may be a terribly skinny wire. W lamps should be replaces once the W filament breaks. associate degree crystal rectifier contains a really little semiconductor (diode) that's encapsulated in epoxy and this half emits lightweight once electricity flows through it. LED's om flashlights ar wide thought of "unbreakable" and not replaced – a period lamp.

6 - Lens The lens is that the clear, plastic half you see on the front of the torch that protects the lamp, since the lamp is created if glass and may simply be broken.

7 - Batteries once activated, the batteries are the ability supply for your torch.

Whether you’re outdoors for a nighttime journey or end up within the dark from an influence outage when a storm, the convenience of moveable lightweight is as shut as a straightforward button on your torch. however simply however will a torch work?

How do of these torch elements work together?


When the switch of a torch is pushed into the ON position, it makes contact between 2 contact strips, that begin a flow of electricity, battery-powered from the battery. The batteries are connected in such the simplest way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery. The batteries rest atop atiny low spring that's connected to a contact strip. The contact strip runs down the length of the battery case and makes contact with one facet of the switch. there's another flat contact strip on the opposite facet of the switch, that runs to the lamp (light bulb), providing associate degree electrical affiliation. there's another half connected to the lamp that produces contact with the positive conductor of the highest battery, therefore finishing the circuit to the lamp and finishing the generation of electricity. One find here different shows about tactical flashlight.

When activated by electricity, the W filament or crystal rectifier within the lamp begins to glow, manufacturing lightweight that's visible. This lightweight reflects off of the reflector that's positioned round the lamp. The reflector redirects the sunshine rays from the lamp, making a gradual beam of sunshine, that is that the lightweight you see emitting from the torch. a transparent lens covers the lamp on your torch so the glass on the lamp doesn't get broken.

When the torch switch is then pushed into the OFF position, the 2 contact strips ar physically stirred apart and also the path for the electrical current is broken, therefore ending the assembly of sunshine, and turning your torch off.

All of the on top of elements should be connected and in situ so as for the moveable torch to figure. Otherwise, you've got associate degree electric circuit and also the electricity won't flow.

Packing, Seals and Gaskets

Packing, seal and gasket resists the flow of fluid from machinery face, head, joint and machinery gap or clearance. Packing materials: Fiber, asbestos, cotton, synthetic materials, plastic, Teflon, graphite etc. Packing structure: Twisted, Braided and Consolidated. Gasket:             A gasket is a mechanical seal that fills the space between two mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow " less-than-perfect " mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials, such as gasket paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer (such as polychlorotrifluoroethylene)                                                                                                Figure : Gaskets Name of the gasket                       uses

Why a dc generator fails to build up voltage?

How can the problem be remedied : No residual magnetism, reversed field connection and high resistance of field circuit are responsible for the failure of build up process of a dc generator. The factors are explained below: No residual magnetism:    For the starting build up process requires some residual magnetism in the magnetic circuit then no voltage will be generated that can produce current flow through field circuit. Reversed field connection:    The voltage induced inside the coil of field circuit due to residual magnetism that can permit the flow of current. For the following direction of this flux will be created and the direction of this flux will be same direction as the residual flux. If the field connections are reversed the lines of flux produced by current flow will oppose the residual flux, as a result generate voltage will decrease rather than increase. So voltage build up process failed. Field circuit resistance too high:   A field

what is the difference between long shunt and short shunt dc generator?

How do they differ from normal generator?    Draw their V-I characteristics and explain them? In short shunt connection the shunt field is connected directly across the armature terminals and the armature connection equals the sum of the shunt field current plus the load current . In this instance the load current flow s through the series field winding so that the load current and series field current are one and same.              In long shunt connection the voltage across the shunt field is the same as the terminal voltage of the generator and current in the armature will be the current in the series field. The armature current equals the shunt field current plus the load current.   A shunt generator has the field circuit connected directly across the armature. As more devices connected in parallel the load on the generator increases that the generator current increases which results decrease in terminal voltage of the generator.

Various Methods of Drawing Flow Nets

  1.       Hydraulic models: a.        Streamlines can be traced by injecting a dye in a seepage model or Heleshaw apparatus. b.       They by drawing equipotential lines the flow net is completed. 2.       Analytical Method: a.        It is only applied to problems with simple and ideal boundaries conditions. b.       The equation corresponding curve Ç¿ and Ñ° are first obtained and the same are plotted to give the flow net pattern for the flow of fluid between the given boundary shape. 3.       Electrical Analogy Method: This method based on the fact that the flow of fluids and flow of electricity through a conductor are analogus. These two systems are similar in the respect that electric potential is analogus to the velocity potential. The electric current is analogus to the velocity of flow and the homogeneous conductor is analogus to the homogeneous fluid. This method only for a practical method of drawing a flow net for a particular set of boundaries.

Which type of Battery connection Series or Parallel Connection is used for Diesel Generator?

Diesel Generator Battery Connection Batteries can emit explosive gases.     To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To remove the possibility of arching, remove the negative battery cable is first and attach the negative battery last. When using jumper cables to start the engine make sure to connect the cables in parallel Positive to positive and negative to negative.

“Equalizer connection is needed in lap winding armature but not in wave winding “ why ?

 The equivalent circuit of a four point – pole dynamo with a simplex winding. The voltage induced in each path is assumed to both to be same and should be if the reluctance of each magnetic path is the same, so that the lines of flux cut by each inductor of each path are the same. However wear of the bearings or deflection of the armature shaft may cause the armature to be closer to some poles and farther from others, thus changing the length of the air gap, and therefore the reluctance of the magnetic circuits of the poles is not identical. This factors cause the voltage in the materials making up the magnetic circuit. These factors cause the voltage in each parallel path differ, and the unequal voltages in turn cause flow of a circulating   current through the windings and brushes , undue heating of the armature and waste the power. To reduce the circulating current, points on the winding which should be at the same potentials are brought to the same potentials by connecting
