Current, resistance and potential difference (AQA GCSE Physics): Flashcards

Current is directly proportional to potential difference (at constant temperature)

Ohms (Ω)

Less current flows

More current flows

Always have the same resistance value

Resistance can be changed using a slider or knob

$V = I \times R$

$I = \frac{V}{R}$

$R = \frac{V}{I}$

Straight line through the origin
