Question: A potential difference V(t) = V_{0}\ \text{sin}\ \omega t is maintained across a parallel-plate capacitor with capacitance _C_ consisting of two circular parallel plates. A thin wire with resistance _R_ connects the centers of the two plates, allowing charge to leak between plates while they are charging.   (a) Obtain expressions for the leakage current I_{\text{res}}(t) in the thin wire. Use these results to obtain an expression for the current I_{\text{real}}(t) in the wires connected to the capacitor.   (b) Find the displacement current in the space between the plates from the changing electric field between the plates.   (c) Compare I_{\text{real}}(t) with the sum of the displacement current I_{\text{d}}(t) and resistor current I_{\text{res}}(t) between the plates, and explain why the relationship you observe would be expected.
