11.8 Resistor Capacitor (RC) Circuits
IntermediateMCQMathematical15.9k
A schematic diagram of a parallel circuit. On the left vertical branch, a circle with a single arrow pointing upward inside it is labeled I_0. Connected in parallel to its right across top and bottom horizontal wire rails are two vertical branches: the middle branch contains a zigzag resistor labeled R, and the rightmost branch contains two parallel vertical lines representing a capacitor labeled C. No other components or labels appear.
Parallel RC circuit connected to a constant current source.
An ideal current source delivering a constant total current \(I_0\) is connected in parallel with an uncharged capacitor of capacitance \(C\) and a resistor of resistance \(R\) at time \(t = 0\). Which of the following expressions correctly gives the potential difference \(V(t)\) across the capacitor as a function of time \(t\) for \(t \ge 0\)?
