Answer 2

Concept:

Inductance is the tendency of an electrical conductor to resist a change in the flow of current through it.

The waveform's phase angle, measured in degrees or radians, indicates how far left or right the waveform has moved relative to the reference point.

The flow of electric charge that periodically reverses direction is known as alternating current (ac). According to Induced Electric Fields, an alternating electromagnetic field (emf) that is generated in a power plant is what creates an ac.

Given:

The inductance of the inductor is 9.50 mH is connected across an ac source with a voltage amplitude 45 V.

Find:

The phase angle for the source voltage with respect to the current.

Solution:

An inductor with inductance, L = 9.50 mH

The voltage amplitude, $V_L=45 V$

A 90° phase angle exists between the voltage and the current in an inductor. As a result, the source voltage leads to the current and the phase angle is ϕ = 90 degrees.

The phase angle for the source voltage relative to the current is 90 degrees.
