Series & Parallel Circuits (OCR GCSE Physics A (Gateway Science Suite)): Flashcards

$R_{\text{total}} = R_1 + R_2 + ...$

Current must pass through each resistor

Sum of the individual resistances

$\frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + ...$

Always less than the smallest individual resistor

Current has multiple paths to take

Total resistance decreases

Ohms ($\Omega$)
