How to Test a Capacitor Using Digital and Analog Multimeter?
In case of absence of DC source (like batteries), the high rated capacitors (i.e. fan capacitors rated for. 3.5µF, 120, 230 or 400V) you may use 120-230V AC, but you have to connect a series of resistors (say 1kΩ~10kΩ, 5~50Watts) to connect between capacitor and 230V AC supply. This way, it will reduce the charging and discharging current.
