You are working in a factory that uses many motors. your supervisor is pointing out a motor to you that shows signs of weakness and may suddenly seize, so that the rotor suddenly stops rotating. the motor in normal operation carries a direct current of 0.750 a when connected to a 120 v power supply. the resistance of the motor windings is 19.6 ω. your supervisor asks you to determine by what factor the rate of change of internal energy in the windings will increase if the rotor seizes while it is operating and the supply voltage is not cut off.
