Resistors in Series

Total resistance of resistors in series.

Formula

Req=R1+R2+⋯R_{eq} = R_1 + R_2 + \cdots

Variables

R_iIndividual resistances

Example

Resistors of 2 Ω and 3 Ω in series total 5 Ω.

Did You Know?

Resistors in series simply add up — the current has only one path through them all.
