Explanation / Answer
Given resistances R1 = 86 R2 = 67 voltage across R1 resistance = 27 V equivalent resistance of the circuit R = R1 +R2 = 86 + 67 = 153 current through each resistance is equal because they areconnected in series combination I = V 1 / R1 = 27 / 86 = 0.3139 A So voltage across R2 resistor V2 = I R2 = 0.3139 * 67 = 21 V
