What formula best describes the true power consumed by an induction motor?

The formula that best describes the true power consumed by an induction motor is represented by the product of current, voltage, and the power factor. This relationship is essential in electrical engineering as it reflects how much actual power is being used to perform work in the motor.

True power, often measured in watts, takes into account not just the voltage and current but also the phase difference between them, which is represented by the power factor. The power factor indicates how effectively the electrical power is being converted into useful work output. In the case of an induction motor, which is an AC motor, the power factor is critical, as it influences the efficiency of the motor and the quality of the electrical installation.

The significance of each component within the formula can be elaborated as follows:

• Current represents the flow of electricity through the motor.

• Voltage refers to the potential difference that drives this current.

• The power factor is a measure of how much of the electrical power is effectively converted into useful mechanical power.

By multiplying current, voltage, and the power factor together, you obtain the true power in watts, which accurately reflects the actual energy consumption of the induction motor that results in mechanical output.

This understanding directly aligns with how induction motors operate in real-world applications, ensuring
