a resistor, the component with coloured rings, which tells you what value it has. (the higher value, the more current it prevents)

What would happen if there is no an electric switch in a curcuit?

Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.


What is the function of fuse?

In electrical engineering, a safety device that protects electric circuits from the effects of excessive electric currents. A fuse commonly consists of a current-conducting strip or wire of easily fusible metal; whenever the circuit is made to carry a current larger than that for which it is intended, the strip melts to interrupt it.


What is a device used to open and close an electric circuit?

The device is called a switch.


How does a switch control an electric device?

A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
