AP Physics 2
11.8 Resistor-Capacitor (RC) Circuits
BeginnerMCQMathematical24k
A simple single-loop circuit schematic consisting of two parallel vertical branches connected at the top and bottom by horizontal wires. The left branch contains a capacitor labeled C = 10 microfarads. The right branch contains a resistor labeled R = 3.0 ohms. No battery or external voltage source is present in the loop. No directional arrows or other labels appear.
Discharging RC circuit loop.
A \(10\text{ }\mu\text{F}\) parallel-plate capacitor is fully charged by connecting it to a \(12\text{ V}\) ideal battery. The capacitor is then disconnected from the battery and connected across a \(3.0\text{ }\Omega\) resistor to form a single closed loop. What is the instantaneous current through the resistor immediately after the loop is closed?
