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?

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.

To calculate the resistance in the air conditioner, you can use Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). In this case, the voltage is 110 volts and the current is 7.50 amperes.

So, the formula becomes: R = V / I

Substituting the given values, you get: R = 110 volts / 7.50 amperes

Calculating this expression, the resistance in the air conditioner is approximately 14.67 ohms.
