Capacitance Calculator
Calculate capacitance from charge and voltage using C = Q/V. Also computes energy stored in the capacitor.
Enter any two values to find the third.
Enter two values.
Capacitance Formula
C = Q / V
Energy stored: E = ½CV²
Energy stored: E = ½CV²
Example: Q = 0.005 C, V = 10 V
C = 0.005/10 = 0.0005 F = 500 μF
C = 0.005/10 = 0.0005 F = 500 μF
FAQ
What is a farad?
1 farad is extremely large. Practical capacitors range from picofarads (pF) to microfarads (μF) to millifarads (mF).
