Solve the problems below:
1. There is a light bulb in a 120. V circuit with a resistance of 100. ohms. What is the current through the bulb?
2. What is the weekly energy cost of leaving a 65 W bulb on for half the day if the electricity cost is $0.15 per kWh?
3. An electric motor draws a current of 12 A in a 240 V circuit. What is the power of this motor in W?
4. The step-down transformer in a local neighborhood reduces the voltage from a 7,200 V line to 120 V.
