Formula Used

P = V × I

For direct current (DC), power in watts is voltage multiplied by current.
P = V × I

For alternating current (AC), we multiply by the Power Factor (PF).
P = V × I × PF

Line-to-Line Voltage (V_LL):
P = √3 × V × I × PF (approx 1.732 × V × I × PF)

Line-to-Neutral Voltage (V_LN):
P = 3 × V × I × PF
