What is the formula to calculate capacitor size for an electric motor?

The formula to calculate the required capacitor size for an electric motor is typically given by:

[ C = \frac{(k \times P)}{V^2} ]

where ( C ) is the capacitance in microfarads (µF), ( P ) is the power of the motor in watts, ( V ) is the voltage, and ( k ) is a constant that varies depending on the motor type (usually around 1.0 to 1.5 for single-phase motors). It's important to consider the motor's operating conditions and consult manufacturer guidelines for precise capacitor sizing.
