SERIES AND PARALLEL CONNECTION
Chapter 3 SERIES AND PARALLEL CONNECTION Series and parallel combination of resistances Resistors are in series whenever the flow of charge, or the current, must flow through components sequentially. The total resistance in the circuit is equal to the sum of the individual resistances. The total resistance in a parallel circuit is equal to the sum of the inverse of each individual resistance. R series_total = R1 + R2 + R3 + R4 1/R parallel_total = 1/R1 + 1/ R2 + 1/R3 + 1/R4
