Gear Motor

A gear motor is a combination of a gearbox and an electric motor. This combination of two systems is used for efficient usage of the motor. It makes a cost-effective solution for high torque, low-speed applications. These motors are used in our household as, garage door openers, alarm clocks. In commercial areas, hospital beds, cranes.

Question

Upon being started, a motor draws additional current until the motor is
running. A large fan motor draws 3.45 amperes of current when running.
When starting, the fan motor draws an additional 9.27 amperes of starting
current. What is the total current drawn by the fan motor while starting?
