Stored Charge vs Capacitance

Capacitor Charge

Q = C x V

Where Q is charge in coulombs, C is capacitance in farads, and V is voltage. A larger capacitance or higher voltage stores more charge.

Example Calculation

100 uF capacitor charged to 12 V.

  1. 01Q = 100 uF x 12 V = 1200 uC
  2. 02Q = 0.0001 F x 12 V = 0.0012 C
