1. Use a multimeter to measure the resistance of any two of the three wires. Find the MAX resistance and mark it with AC;
2. Connect the capacitor to AC;
3. Find the 2 wires with MIN resistance value (AB or BC) and connect them to the 220 power supply.
If the electric fan rotates reversely, connect the 220 power supply to 2 wires with slightly larger resistance values.
Capacitors, usually referred to as capacitors, are represented by the letter C.Definition 1: A capacitor, as its name suggests, is a 'container of electricity', a device that holds electric charge. English name: capacitor.Capacitors are one of the electronic components widely used in electronic equipment. They are widely used in DC isolation, coupling, bypass, filtering, tuned loops, energy conversion, control and other aspects in circuits.Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and very close to each other form a capacitor.
Capacitance is different from capacitor. Capacitance is a basic physical quantity with the symbol C and the unit is F (Farad).
General formula C=Q/U Special formula for parallel plate capacitors: inter-plate electric field strength E=U/d, capacitance determining formula C=εS/4πkd
With the rapid development of electronic information technology, digital electronic products are being updated at an increasingly faster rate. The production and sales of consumer electronics products, mainly flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products, continue to grow, driving the growth of the capacitor industry.
