Parallel circuit rules
-
Components in a parallel circuit share the
same voltage. Etotal = E1 = E2
= . . . En
-
Total resistance in a parallel circuit is
less than 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 + . . . In
