Answer 1

Concept

Phase difference is used to describe the difference in degrees or radians when two or more alternating quantities reach their maximum or zero values.

Step 1: Consider any one term (either sin or cos) as a reference phasor.

Step 2: Plot the given quantity with respect to the reference phasor.

Step 3: Start moving in the anticlockwise direction. The quantity that comes first is said to be leading with respect to other quantity.
