What is the back electromagnetic field

Reference no: EM13558413

The coils of a motor's rotor have resistance of 2.0 Ω. When the motor runs at full speed, powered by 115V linevoltage it draws a current of 9A.

What is the back electromagnetic field (emf) in this motor under those conditions?
If the motor is prevented from turning, what would be the current drawn?
How much more heat would be generated in the coils in that situation?
