How to Calculate and Solve for Phase Lag | Electromagnetic Method

The image above represents phase lag.

To compute for phase lag, three essential parameters are needed and these parameters are Frequency (f), Inductance (L) and Resistance (R).

The formula for calculating the phase lag:

φ = tan-1 (2πfL/R)

Where:

φ = Phase Lag
f = Frequency
L = Inductance
R = Resistance

Let’s solve an example;
Find the phase lag when the frequency is 20, the inductance is 32 and the resistance is 18.

This implies that;

f = Frequency = 20
L = Inductance = 32
R = Resistance = 18

φ = tan-1 (2πfL/R)
φ = tan-1 (2π(20)(32) / 18)
φ = tan-1 (4021.23 / 18)
φ = tan-1 (223.40)
φ = 89.74°

Therefore, the phase lag is 89.74°.
