Current, Resistance & Potential Difference (OCR GCSE Physics A (Gateway Science Suite)): Flashcards

Driving force causing charges to flow

Volts (V)

Voltmeter

Parallel with component

Slows flow of electrical charges

Ohms ($\Omega$)

$V = IR$

Potential difference in volts (V)

Current in amps (A)

Resistance in ohms ($\Omega$)

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

Directly proportional

Passes through origin
