Question:

Once the switch in the circuit in Figure P31.25 is closed, the circuit can be used to charge the capacitor. Sketch the electric field inside wire $\mathrm{A}(a)$ when the switch is open, $(b)$ at the instant just after the switch is closed, and $(c)$ at some instant long after the switch is closed.

Data from Figure P31.25
