Capacitance question bank (Physics)

In an ideal LC circuit, if the energy stored in the inductor is equal to energy stored in a capacitor, then the magnitude of charge Q stored in capacitor is ( $Q_0$ is the maximum charge)

A parallel plate capacitor with capacitance $1\ \mu\text{F}$ is being charged at a rate such that the potential difference across it changes at $10^6\ \text{V/s}$. The instantaneous displacement current between the plates is
