Problem
A battery supplies a constant emf of 12.0 V to a series circuit containing a 10 Ω resistor and one additional resistor. The current measured in the circuit is 0.50 A, and the potential drop across the 10 Ω resistor is found to be 5.0 V. To satisfy the condition that the sum of potential differences around the loop is zero, what must be the potential drop across the second resistor?
(a) 6.0 V
(b) 7.0 V
(c) 5.0 V
(d) 10.0 V
