Electric Current

A measurement of the rate of flow of an electric charge through an electrical conductor

(a)  

A substance that is able to carry an electrical charge

(a)  

• A substance that does not allow an electrical current to flow through it

assumes that current flows out of the positive terminal through the circuit and into the negative terminal of the source

(a)  

The amount of energy supplied by an electrical source to each unit of electric charge

(a)  

Electric charge is measured in?

(a)  

• Electric Current is A measured in ?

• The difference in the electrical potential energy between any two points in a circuit

• The ratio of voltage (V) across a component to the current (I) flowing through it (R = V/I) [measured in ohms (Ω)]
