Electricity Revision

Current is...

• the flow of charge (electrons) measured in amps (A)

• the amount of energy that each electron has measured in volts (V)

• the difficulty of the flow of charge (electrons) measured in ohms (Ω)

Potential difference is...

• the flow of charge (electrons) measured in amps (A)

• the amount of energy that each electron has measured in volts (V)

• the difficulty of the flow of charge (electrons) measured in ohms (Ω)

Resistance is...
