Customer ServiceVery few real loads are capacitive, so a capacitor is added to the circuit. With a 45° phase shift, the power factor is 0.707, and we are drawing 1.42A from the mains instead of 1A. To restore the current so that it is in phase with the voltage, we need to add a capacitor to the circuit. A capacitor is effectively the opposite of an inductor
Customer ServiceOpen Circuit: If the bulb doesn''t light at all, the capacitor is likely open-circuited, blocking current flow. Short Circuit: If the bulb''s brightness is unchanged from direct connection to 220V, the capacitor may be short-circuited, allowing full current flow. This method is best for quick testing of high-voltage, high-capacitance capacitors. Use a low-wattage incandescent bulb (e.g., 15W
