Thickness Length

Thickness and Length:

If you have a circuit with a short wire then the light will be brighter than if it was longer.
If you have a circuit with a fat wire then the light will be brighter than if it were thinner. The way the width works is; imagine the wire is a pipe and the electrons are water, more water can fit in a thicker pipe than a thinner one. The way the length works is; imagine the wire is a running track and the runners are electrons, it takes longer to run round a longer track.

Switches

Switches:

Switches turn the electric flow on and off. Like these pictures.In a parallel circuit if switch one is off then the circuit is incomplete but if you turn switch two or three off it will only cut off the electic flow to the light on the same level.

Electric Flow

Electric Flow:

Electron move and pass energy to each other

Circuit Symbols

If you take some Cells, Wires and some lamps you can make a Parallel circuit or a Series circuit.
