Use the information and table below to answer the following question. A student is studying household electricity use and cost. She collects data for three household appliances in her home and records the data in the table below. Voltage Used (V) Appliance Current Used Number of hours (Amps) powered per day refrigerator 4 120 3.0 hrs microwave 8. 120 0.10 hrs stove 9. 240 0.50 hrs If the cost per kW-hr is the same for all three appliances, how could the three household objects be ranked from MOST expensive to least expensive to use?

Construct Your Own Problem Consider a battery used to supply energy to a cellular phone. Construct a problem in which you determine the energy that must be supplied by the battery, and then calculate the amount of charge it must be able to move in order to supply this energy. Among the things to be considered are the energy needs and battery voltage. You may need to look ahead to interpret manufacturer’s battery ratings in ampere hours as energy in joules.
. All of the electrical outlets in a room are connected in a single parallel circuit (Figure 7.38). The circuit is equipped with a 20-A fuse, and the voltage is 120 V. (a) What is the maximum total power that can be supplied by the outlets without blowing the fuse? (b) How many 1,200-W appliances can be plugged into the sockets without blowing the fuse?
Shown below are the results of an experiment where four devices were connected across a variable voltage source. The voltage is increased and the current is measured. Which device, if any, is an ohmic device?
Check Your Understanding Handheld calculators often use small solar cells to supply the energy required to complete the calculations needed to complete your next physics exam. The current needed to run your calculator can be as small as 0.30 mA. How long would it take for 1.00 C of charge to flow from the solar cells? Can solar cells be used, instead of batteries, to stall traditional internal combustion engines presently used in most cars and trucks?

Make a sketch of an electric circuit that contains a switch and two lightbulbs connected in such a way that if either bulb burns out the other still functions, but if the switch is turned off, both bulbs go out.
The average television is said to be on 6 hours per day. Estimate the yearly cost of electricity to operate 100 million TVs, assuming their power consumption averages 150 W and the cost of electricity averages 12.0 cents/kW h .
Combine Ohm’s law and the equation for power consumption to derive the equation that gives the power in terms of current and resistance. Use the result to answer the following question. A cable carrying electrical energy wastes 10 kWh of energy each day because of ohmic heating. If the current in the cable is doubled but the cable’s resistance remains the same, how much energy will it waste each day?
