12. an electric motor is plugged into a standard wall socket and is run- ning at normal speed. suddenly, some dirt prevents the shaft of the mo- tor from turning quite so rapidly. what happens to the back emf of the motor, and what happens to the current that the motor draws from the wall socket? (a) the back emf increases, and the current drawn from the socket decreases. (b) the back emf increases, and the current drawn from the socket increases. (c) the back emf decreases, and the current drawn from the socket decreases. (d) the back emf decreases, and the current drawn from the socket increases.
