We then short-circuit this series combination by closing the switch. As soon as the capacitor is short-circuited, it starts discharging. Let us assume, the voltage of the capacitor at fully charged condition is V volt. As soon as the capacitor is short-circuited, the discharging current of the circuit would be – V / R ampere. ...

Multilayer ceramic capacitors (MLCCs) have broad applications in electrical and electronic systems owing to their ultrahigh power density (ultrafast charge/discharge rate) and excellent stability (1–3).However, the generally low energy density U e and/or low efficiency η have limited their applications and further development …
where W is the energy stored on the capacitor, measured in joules, Q is the amount of charge stored on the capacitor, C is the capacitance and V is the voltage across the capacitor. As seen from the above equation, the maximum amount of energy that can be stored on a capacitor depends on the capacitance, as well as the maximum rated …
