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.
Understanding Current-Voltage Curves
Capacitors and inductors are fundamentally different in that their current-voltage relationships involve the rate of change. In the case of a capacitor, the current through the capacitor at any given moment is the product of capacitance and the rate of change (i.e., the derivative with respect to time) of the voltage across the capacitor.
