When you are converting an instantaneous current to a phasor, how does the phase angle being positive or negative affect solving the problem i.e. the representation being (wt - the phase angle in degrees) or (wt + the phase angle in degrees)?

Question

When you are converting an instantaneous current to a phasor, how does the phase angle being positive or negative affect solving the problem i.e. the representation being (wt - the phase angle in degrees) or (wt + the phase angle in degrees)?

Step 1

The overall solution depends on the phase angle or epoch (initial phase) of the instantaneous form of current. In this case, with the help of an example, this will be illustrated. 

Step 2

Suppose, the instantaneous current is expressed as
