Usually, two types predominate. The first is pulsed, in which the mains voltage is rectified and then powers a pulse generator of a higher frequency, from the secondary voltage of which the output […]

What is a Capacitor Most radio components can be divided into two groups passive and active . And the capacitor must be attributed to the first group of passive components. In theory, any capacitor can be represented as two plates separated by an insulator. They are characterized by capacity. The unit of capacitance is the farad (F), defined as one coulomb per […]
