Ceiling Fan Regulator/AC dimmer

Ceiling Fan Regulator/AC dimmer

Electronic Ceiling Fan Regulator AC Light Dimmer circuit We first discuss the conventional big size resistive fan regulator. Conventional Old ceiling fan regulators use 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 a full resistor load between load and source to […]

What is Impedance, Impedance vs Resistance

What is Impedance, Impedance vs Resistance

 Resistance vs Impedance 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 the same (constant) at any different frequency range. Impedance is related to the […]

Semiconductor P-N Diode | P-N Junction

P-N Junction Diode  A diode is the two-terminal polarised electronic semiconductor device. One terminal is Anode(-) and the other is Cathode(+). The cathode is marked with the silver colour or colour band. This is the simplest semiconductor device but this is very important and most useful in electronic circuits. Diode Function The main function of the semiconductor diode is the […]
