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.
Capacitors | Brilliant Math & Science Wiki
16 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured …
