Circuit with junctions where current divides and rejoins
Same for all, equals supply voltage

1Req=1R1+1R2+...\frac{1}{R_{\text{eq}}} = \frac{1}{R_1} + \frac{1}{R_2} + ...Req1=R11+R21+...
Req=R1×R2R1+R2R_{\text{eq}} = \frac{R_1 \times R_2}{R_1 + R_2}Req=R1+R2R1×R2
Always smaller than smallest individual resistor
Req=RnR_{\text{eq}} = \frac{R}{n}Req=nR
Carries more current
Voltage is constant; add currents
Series: voltages add. Parallel: currents add
