|
|
Electrical Load |
A device that converts electrical energy to another the light bulb converts electrical energy to light and heat. |
|
|
Electrical current |

|
|
Ohm's law |
The Electrical Potential Difference (V) between two points in an electric circuit is proportional (equal) to the current (I) times the resistance (R) flowing through the conductor. |
|
|
Resistance in a circuit |
The greater the resistance of a component the smaller it’s conductivity |
|
|
Resistance |
The degree to which a substance opposes the flow of electric current through it. |
|
|
Conductors |
Objects that allow the flow of electrons more freely and have low resistance |
|
|
Insulator |
Object that electron flow greatly and have High resistance values. |
|
|
Short Circuits |
If a battery is connected, with no load to use up the, electrons energy, it can become very hot and start a fire. |
|
|
A full Circuit reacquires |
A switch, Energy source, Cell. |
|
|
Primary Cells |
Electric cells that can not be recharged because the chemical reactions that produce the flow of electrons are not reversible. |
