Electronic Ceiling Fan Regulator/AC Light Dimmer circuit We first discuss about the conventional big size resistive fan regulator.Conventional Old ceiling fan regulators uses resistive wire to connect in series and there are multiple points to connect the regulating knop switch to adjust the speed. This type of regulator works on fully resistor load between load and source to make a […]
What is impedance Impedance (Z) is similar to Resistance (R) . Impedance and Resistance both oppose the current in circuit. Both are almost the same thing , But resistance related to DC Circuit. Resistance oppose the steady electric current in DC circuit. Resistance remains same (constant) at any different frequency range. Impedance is related with AC circuit. Impedance vary […]
