Fundamentals | Capacitor Guide
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
How does a capacitor store energy? Energy in Electric Field
The energy stored in a capacitor can be calculated using the formula E = 0.5 * C * V^2, where E is the stored energy, C is the capacitance, and V is the voltage across the capacitor. To convert the stored energy in a capacitor to watt-hours, divide the energy (in joules) by 3600.
