Does a charging capacitor emit an electromagnetic wave?

2 Answers. Charging and discharging a capacitor periodically surely creates electromagnetic waves, much like any oscillating electromagnetic system. The frequency of these electromagnetic waves is equal to the frequency at which the capacitors get charged and discharged. That means that if you have just DC, the frequency is de facto …

8.4: Energy Stored in a Capacitor

The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors.
