How to Calculate Capacitor Charge

Calculate charge, capacitance, or voltage for a capacitor.

The Formula

Q = C × V

The capacitor charge formula uses the mathematical relationship: Q = C × V. Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the capacitor charge calculation.
  2. 2Substitute your known values into the formula: Q = C × V.
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
  5. 5Verify using the interactive Capacitor Charge Calculator to confirm your answer.
