How Capacitors Work
Inside a capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper (and some …
Understanding ESR and ESL in Capacitors
Another theoretical way to calculate ESR of the capacitor is to measure the Ripple voltage and Ripple current of the capacitor and then the ratio of both will give the value of ESR in the capacitor. However, a more common ESR measurement model is to apply alternating current source across the capacitor with an additional resistance.
