Physics - Chap 8

Direction of current, flowing from positive to negative terminal

A charged particle that may be contributed to an electric current. (protons, electrons, ions)

Rate of flow of an electric charge past a point (A)

I = Q / t

Charge that flows past a point in a circuit, in time of 1s and current of 1A

The magnitude of a charge.

1.6 × 10^-19

The energy transferred per unit charge as the charge drives around a complete circuit.

Energy given to the charge by the supply

The energy transferred per unit charge as it moves between 2 points in a circuit.

Charge loses energy to other sources.

Ratio of potential difference to current

R = V / I

The resistance of a component when p.d of 1 V drives a current of 1A through it

The rate at which energy is transferred

P = VI

P = I²R

P = V²/R

P = VIt
