An AC voltage source delivers current to Load A and Load B which are connected in parallel. Current in Load A is 25 A and Current in Load B is 42.2. If the current in load B leads the current in load A by 45 degrees, calculate: a) Resultant or total current, b) Angle between the resultant current and Load current A if Load Current A is at reference or zero degrees.
