A 150 mH Inductor in a Circuit: Phase Angle Calculation

Phase Angle Calculation

The phase angle between the current and the voltage can be calculated using the formula:

Phase Angle = arctan(X_L / R)

Given that the circuit is purely inductive, the resistance (R) is 0.

Therefore, the phase angle is:

Phase Angle = arctan((2πfL) / 0)

Substitute the given values:

Phase Angle = arctan((2 * 3.14159 * 60 * 0.150) / 0)

Phase Angle = arctan(56.548) = 90 degrees

Hence, the phase angle between the current and the voltage in the circuit is 90 degrees.
