Modelling Resistance in Parallel Circuits (VCE SSCE Physics): Flashcards

Circuit with junctions where current divides and rejoins

Same for all, equals supply voltage

$I_1 + I_2 + I_3 + ... + I_n$

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

$R_{\text{eq}} = \frac{R_1 \times R_2}{R_1 + R_2}$

Always smaller than smallest individual resistor

$R_{\text{eq}} = \frac{R}{n}$

Carries more current

Voltage is constant; add currents

Series: voltages add. Parallel: currents add
