Here is an example of a low-voltage battery being used to create some light.
00:00:01
Connecting a light bulb to this battery, we have created a circuit, a path for electrons to travel on.
00:00:06
Our light bulb does two things.
00:00:12
It introduces some resistance into the circuit, reducing the flow of electrons so that the copper wires won't get hot,
00:00:15
and it converts electrical energy into light energy.
00:00:21
Our circuit also demonstrates a switch, a device for turning the electricity off and on.
00:00:25
The switch does this by creating an opening in the circuit.
00:00:31
This is an actual circuit similar to the one in the animation.
00:00:35
The wires I'm using have metal alligator clips connected to their ends
00:00:44
making it easy to connect. The metal in these wires is covered in plastic.
00:00:49
Plastic is an electrical insulator. The current from our low voltage battery
00:00:54
will not flow through the plastic but easily travels in the copper wire under
00:00:59
the plastic.
00:01:03
Connecting and disconnecting the wire creates a simple switch turning the
00:01:04
light off and on. A wall switch does the same thing. The plastic lever and cover
00:01:12
plate protect you from the high voltage used in this circuit.
