If the electric fan capacitor uses 1.5UF or 2UF, it may be an AC fan, and this capacitor is the starting capacitor of the AC fan motor. If the power supply part is a resistor-capacitor step-down, it may be a capacitor used for step-down. Two capacitors are introduced separately. 1. If the resistance-capacitance step-down is used, [...]
