A diagram represents a simplified sketch of an electric DC motor.which contains a magnet, commutator, carbon brushes, coil and a pivot. when the electric motor is connected to a 12V DC supply, it draws a current of 1,2A. The motor is now used to lift an object of mass 1,6kg through a vertical height of 0,08m at constant speed in 3s. IS ALL THE ELECTRICAL ENERGY CONVERTED TO THE GAIN IN POTENTIAL ENERGY OF THE OBJECT? SUPPORT YOUR ANSWER WITH RELEVANT CALCULATIONS.
