Question

At what rate must the potential difference between the plates of a parallel-plate capacitor with a 2.0uF capacitance velocity changed to produce a displacement current of 1.5A

Answer 1

$$I=C\frac{dU}{dt}$$

$$\frac{dU}{dt}=\frac{I}{C}$$

$$\frac{dU}{dt}=\frac{1.5}{2\cdot 10^{-6}}=7.5\cdot 10^5\frac{V}{s}$$
