Question { 15743 }

Why we use cosine angle for calculating power factor not in
sine angle ?


Answer

See its because when there is no power lag, that is when the phase shift is 0 your other parameters shouldn't affect by the cos (phi). So when Phi=0 then cos (phi)=1. Therefore its much convenient to choose cosine rather than sine angles.
