MYP Physics Current, Voltage, Power Key Definitions

Definition

Electric current

Electric current is the flow of electric charge through a conductor.

Definition

Electrical power

Electrical power is the rate at which electrical energy is transferred.

Definition

Potential difference (voltage)

The energy transferred per unit charge between two points in a circuit: $V=\dfrac{E}{Q}$.

Definition

Resistance

Resistance is a measure of how much a material opposes the flow of electric charge.
