Q = 1.200 mC, E = 7.200 mJ

Main result for the selected calculation mode.

Charge stored (Q)1.2mC
Energy stored (E)7.2mJ

The capacitor stores 1.200 mC of charge and 7.200 mJ of energy.

  • Charge (Q) is proportional to capacitance and voltage: doubling either doubles the charge.
  • Energy (E) grows with the square of voltage: doubling the voltage quadruples the stored energy.
  • This energy is instantly available for discharge, making capacitors useful for flash photography, power filtering, and hold-up circuits.

Next stepUse the RC Time Constant mode to find how long it takes this capacitor to charge through a resistor.
