Capacitor Energy Using Charge and Voltage

The energy stored in a capacitor depends on the charge and voltage difference across the capacitor.

The energy equals the charge times the voltage divided by 2.

Formula

QuantityVariable["E", "Energy"] == (QuantityVariable["Q", "ElectricCharge"]*QuantityVariable["V", "ElectricPotential"])/2
