# What is the phase angle of the source voltage with respect to the current does the source voltage lag or lead the current?

## What is the phase angle of the source voltage with respect to the current does the source voltage lag or lead the current?

The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage.

How do you find the phase angle of a current?

Multiply 360 (to represent the total number of degrees possible in an angle) by the frequency of your wave. Multiply the number that you receive after multiplying the first two variables by the time delay that was given above.

What does phase angle tell you?

The Phase Angle is the measurement of the functionality of the cell membrane, ie how well our battery is working. If there are leaks in the cell membrane the ability of the cell membrane to hold on to voltage will decrease, thus the Phase Angle will decrease.

### How does the phase angle of an AC resistor work?

When an AC current flows through a resistor, the voltage and current are in phase. However, when you introduce inductance or capacitance, a phase shift occurs and the phase angle depends on the amount of inductive and capacative reactance. When AC current flows through a pure inductor, the voltage leads the current (current lags the voltage) by

What is the phase relationship between current and voltage?

CONCLUSION: In case of pure resistive circuit, the phase angle between voltage and current is zero and in case of pure inductive circuit, phase angle is 90o but when we combine both resistance and inductor, the phase angle of a series RL circuit is between 0o to 90o. Click to see full answer.

When does the voltage and current rise in a resistive circuit?

The voltage and the current in the pure resistive circuit are in phase with each other having no phase difference with phase angle zero. The alternating quantity reaches their peak value at the interval of the same time period that is the rise and fall of the voltage and current occurs at the same time.

#### How does the phase angle of an inductor affect the voltage?

However, when you introduce inductance or capacitance, a phase shift occurs and the phase angle depends on the amount of inductive and capacative reactance. When AC current flows through a pure inductor, the voltage leads the current (current lags the voltage) by 90º.
