A circular parallel plate capacitor has plates of radius 0.1m; the plates are separated by 0.10 mm. A current is supplied to charge the capacitor. While charging, the potential difference across the capacitor increases by 10 V/μs.
What is the magnitude of the rate of change of the electric field between the capacitor plates? Answer= 1 x 10^11 V/m.
What exactly is the "rate of change of the electric field"? dE/dt? dΦ/dt? Φ?
I have tried different methods using all three of those and have yet to receive the correct answer.
I am using: ⌡E.dA = Q/ε for dE/dt
and Φ= Q/ε for dΦ/dt and Φ
