WebUse 2: Gradual Power-Up. You can also use a variac when trying out an unrestored radio or TV for the first time, when its operating condition is unknown. The idea is to set the variac at a low level—say, 50 volts—and then gradually increase the voltage, carefully watching your set for any signs of trouble. Web22 de out. de 2024 · How it Works The basic working of a varicap or a varactor diode can be understood with the following explanation: When a varactor or varicap diode is applied with a rising reverse bias potential, results in an increase in the depletion width of the device, which in turn causes its transition capacitance to decrease.
