Problem
A single-loop circuit consists of an ideal 15 V battery, an 8.0 Ω resistor, and a capacitor. After the circuit has been connected for a long time, the capacitor’s voltage is measured to be 12 V. What is the magnitude of the current in the circuit at that instant?
(a) 0 A
(b) 1.9 A
(c) 0.38 A
(d) 1.5 A
