  • 1.2. SERIES CIRCUIT RULES51.2Series circuit rules• Components in a series circuit share the same current. Itotal = I1 = I2 = . . . In• Total resistance in a series circuit is equal to the sum of the individual resistances, mak-ing it greaterthan any of the individual resistances. Rtotal = R1 + R2 + . . . Rn• Total voltage in a series circuit is equal to the sum of the individual voltage drops. Etotal= E1 + E2 + . . . En1.3Parallel circuit rules• Components in a parallel circuit share the same voltage. Etotal = E1 = E2 = . . . En• Total resistance in a parallel circuit is lessthan any of the individual resistances. Rtotal= 1 / (1/R1 + 1/R2 + . . . 1/Rn)• Total current in a parallel circuit is equal to the sum of the individual branch currents.Itotal = I1 + I2 + . . .
