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.
RF/Capacitance Level Instrumentation
The capacitance unit is the farad, defined as the potential created when a one-volt battery connected to a capacitor causes the storage of one coulomb of electric energy. A pico-farad is one trillionth of that, and the sensitivity of an accurate capacitance detector is 0.5 pF.
