A two-resistor series circuit has an applied voltage of 100 V. The voltage across one of the resistors is 40 V. What is the voltage across the other resistor?
A) 0.4 V
B) 2.5 V
C) 60 V
D) 140 V

Question

Quizplus · Accepted Answer

In a series circuit, the total voltage is the sum of the voltages across each component. Since one resistor has 40 V across it and the total applied voltage is 100 V, the voltage across the other resistor must be 100 V - 40 V = 60 V.
