Zener diode Zener diode is a type of diode which flow of current also in reverse bias and in applications it always connected in reverse bias and zener diode limit the voltage, this diode is used for regulating the voltage in any circuit. It always works in zener breakdown voltage. Zener breakdown voltage is voltage level at this zener diode […]
AC dimmer What is dimmer Dimmer is a circuit that control the voltage level by changing its waveform and gives output minimum or less than the input and make the brightness of light dim or change the speed of fan as required level. AC dimmer is mainly two types, one is manually and second is automatic. In manually dimmer circuit […]
