A device has an average power rating of 1250 W and is designed to operate using a 211 V (RMS) line. The power sockets in your house has a 114 V (RMS) line. Using an ideal transformer that can exactly step up the voltage from 114V to 211 V, find the effective resistance of the device.
A small office-building air conditioner operates on 408-V AC and consumes 50.0 kW. What is the cost of running the air conditioner during a hot summer month when it is on 8.00 h per day for 30 days and electricity costs 9.00 cents/kW.h?
Halogen bulbs have some differences from standard incandescent lightbulbs. They are generally smaller, the filament runs at a higher temperature, and they have a quartz (rather than glass) envelope. They may also operate at lower voltage. Consider a 12 V, 50 W halogen bulb for use in a desk lamp. The lamp plugs into a 120 V, 60 Hz outlet, and it has a transformer in its base. The 12 V rating of the bulb refers to the rms voltage. What is the peak voltage across the bulb?A. 8.5 V B. 12 VC. 17 V D. 24 V

Two different electrical devices have the same power consumption, but one is meant to be operated on 120-V AC and the other on 240-V AC. Assuming its resistance is unaffected, by what factor will the power increase if a 120-V AC device is connected to 240-V AC?
You decide to “go green" and use an exercise bike to power your home appliances. Assume that your exercise bike is rigged to generate electrical power with 60% efficiency. In other words, only 6/10 of the power you develop can be used to store electrical energy for later use. Consider your 3500-Watt central AC unit. You need to run this unit for 4 hours each day during the summer. If you can develop a sustained power of 300 Watts on your exercise bike, how long would you have to work out just to keep the AC running on a summer day?

A 115-W light bulb operates on an effective ac voltage of 110 V. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the effective current through the light bulb?
Cold vaporizers pass a current through water, evaporating it with only a small increase in temperature. One such home device is rated at 3.50 A and utilizes 120 V AC with 95.0% efficiency. (See Figure) How much water must you put into the vaporizer for 8.00 h of overnight operation?
