Good afternoon, I have an exam question I'd like to get assistance. Here is the question:
A MOSFET with an RDS(on)=5milliohm is used to vary the speed of a dc-motor. The motor draws an average current of 12A from a 13V supply if the duty cycle of the switch is 30%. Calculate the average voltage on the motor terminals to one decimal.
