An engine consumes 10kw of power and 4kvar reactive power at a current of (6+j4)Amps . Find the applied voltage in complex form using P=Re(VI) and Q=Im(VI) as simultaneous equations.
Solution : V=(a+jb)
I = 6+j4
VI = (a+jb) ...
The voltage in complex forms are discussed. Simultaneous equations are applied.
