Capacitor Types | Capacitor Guide
Electrolytic Capacitor This is the type of capacitor that uses an electrolyte to achieve a larger capacitance than other types of capacitor. An electrolyte is a liquid/gel that contains a high concentration of ions. Almost all electrolytic capacitor are polarized making the voltage at the positive terminal always greater than the negative terminal.
Capacitor Basic Calculations
Capacitors are used in many circuits for different purposes, so we''re going to learn some basic capacitor calculations for DC circuits. In the paragraph: "If we needed to store a charge of say 0.0002 coulombs then we just divide this by the voltage, in this case 12V to see we need 0.0024 Farads or 2,400uF microfarads."

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.
