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.
An electric field travels over a wire at what speed?
almost the speed of light which is 300 000 kmps i am not sure of an exact figure but i know its close to light speed also the amp-age on the circuit can affect it
When you flip a switch to turn on the light you?
Either close the circuit, or complete the circuit, should work here.
What could be a source of resistance in a household electric circuit?
Heat
What was the first electrical appliance in the world?
The early experimenters developed lights - as arcs and sparks. The first appliance that sold in any numbers was the light bulb; in fact people connected their houses to the electrical supply to get electric lighting.

Used to open and close a circuit?
A light switch
What is the Function of light bulb in an electric circuit?

What is the function of a battery in an electric circuit?
To provide electricity for the bulb to light up.
Why it is often not practical to connect the electric components (example of lights) in series?
In a series circuit, if one of the light's filiments opens the bulb will go out, but along with that light every other device in the same circuit will stop operating.Think of an electric light circuit, in your home, that is controlled by a switch. When the switch is turned off the light goes out. This is an example of a series circuit where ithe switch is in series with the lamp.
