Capacitors & Capacitance Calculations Formulas Equations

Current Through a Capacitor: Current does actually flow ''through'' an ideal capacitor. Rather, charge stored on its plates is given up to the connected circuit, thereby facilitating current flow. Conversely, a net voltage applied to its plates causes a current to flow in the connected circuit as charge accumulates on the plates.

The amount of charge stored in a capacitor is calculated using the formula Charge = capacitance (in Farads) multiplied by the voltage. So, for this 12V 100uF microfarad capacitor, we convert the microfarads to Farads (100/1,000,000=0.0001F) Then multiple this by 12V to see it stores a charge of 0.0012 Coulombs.

How can I determine the current rating of a capacitor?

Put another way, current through a capacitor is inherently AC. Capacitors do often have a ripple current spec. Capacitors designed to be used in applications where this matters, like switching power supplies, will have a ripple current spec. Check out the Panasonic FK series, for example. These are designed for particularly low ESR (for

Capacitor Basic Calculations

The charge held by each capacitor individually is very easy to calculate in series circuits. It''s the same as the total. Each capacitor holds the same number of electrons when in series. That''s because when we charged the capacitors, the current was exactly the same in all parts of the circuit. The same number of electrons that were pushed

The secondary winding of the transformer is 12V, but that''s a nominal RMS AC voltage. The peak voltage is actually higher, and the peak voltage is what charges the capacitor. If the secondary windings operate at 12V RMS, then the capacitor will charge to a peak of about 17V. Thus, at the peak, there is 5V of dropout.
