A current of 7.50 amperes flows through an air conditioner. If the volyage in the wall outlet is 110 volts, what is the resistance in the air conditioner?

Answer 1

Assuming voltage and current are in phase,

effective resistance=110/7.50

Your teacher's use of resistance is really poor. Work is being done on the fluid in the compressor, not being done on resistance. When a motor turns, power is used in not resistance heating, but in delivering a mechanical work to some device. Resistance is a poor term to describe as the electrical load.
