ABSTRACT
R= R1+R2+R3 Thus for a series circuit, the total resistance is obtained by adding together the values of the separate resistances.
Pro b l em 1 . For t he ci rcui t shown i n Fi gure 5.2, determine (a) the battery voltage V , (b) the total resistance of the circuit, and (c) the values of resistance of resistors R1, R2 and R3, given that the p.d.’s across R1, R2 and R3 are 5 V, 2 V and 6 V respectively.
