- The Bezel. The bezel it is just the front part of the flashlight right where the lenses.
- The Head.
- The Battery Compartment.
- The Tail Cap.
- The Light Source.
- The Reflector.
- The Lens.
- The Battery (Power Source)
What is the principle of Torch?
The bulb of a torch is more or less similar to an electric bulb. The only difference is that it light up with a low current of a few volts. The batteries supply this current. As soon as the torch is switched on, the chemical present inside the batteries produces an electric current.
What is the difference between conductor and insulator for Class 6?
A conductor allows current to flow easily through it. An Insulator doesn’t allow current to flow through it. Electric charge exists on the surface of conductors. Electric charges are absent in insulators.
What is insulator with example?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division.
What is difference between open and closed circuit?
An open circuit is defined to be basically a circuit where the energy is not flowing through it. A closed-circuit is defined to be the one where the energy is allowed to flow through it by turning it on. A circuit is made closed if the electricity is flowing from an energy source to the desired endpoint of the circuit.
What is an example of an open circuit?
The definition of an open circuit is a broken path for an electrical current due to an open switch or frayed wire. An example of an open circuit is a string of electric lights that don’t work if one bulb goes out. An electrical circuit that does not conduct current because a switch is open, a wire is broken, etc.
What is an open circuit short answer?
: an electrical circuit in which the continuity is broken so that current does not flow.
What can cause an open circuit?
Open circuits can be caused by one or more of the following:
- broken wire.
- poor connection.
- loose terminal.
- blown fuse.
- tripped circuit breaker.
- faulty switch.
- blown globe.
