Capacitor Energy Using Capacitance and Charge

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

The energy equals the charge squared divided by twice the capacitance.

Formula

QuantityVariable["E", "Energy"] == QuantityVariable["Q", "ElectricCharge"]^2/(2*QuantityVariable["C", "ElectricCapacitance"])

symbol description physical quantity
E capacitor stored energy "Energy"
C electric capacitance "ElectricCapacitance"
Q electric charge "ElectricCharge"
