In a motor for a drill the current lags the voltage by 20.0°. The motor draws an rms current of 6.10 A at a voltage of 150. V rms. What is the motor's power?
Question
Solution 1
The power in an AC circuit is given by the formula P = VIcos(θ), where V is the voltage, I is the current, and θ is the phase angle between the current and the voltage.
In this case, V = 150 V, I = 6.10 A, and θ = 20.0°.
First, we need to convert the phase angle from degrees to radians because the Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
