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 | Number of hours (V) Appliance Current Used (Amps) powered per day refrigerator 4 120 3.0 hrs microwave 120 0.10 hrs stove 6. 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? refrigerator stove >microwave stove refrigerator > microwave refrigerator>microwave > stove 6)microwave stove refrigerator 8.

Two students plan an experiment that connects a bulb to an adjustable voltage source along with a voltmeter and an ammeter to measure the voltage and current. Then they repeated the experiment with a light bulb that has a different resistance. They recorded their data and graphed it on the axes shown. Bulb 1. Bulb Current Graph from: htlpwwww.lkarn.arg.au/ueenee course paresfueenecef04a-de-cireuitr/tccincuits week 2res-valt.currentcanh b/ According to the results of their investigation, which light bulb had a greater electrical resistance? OLight bulb #1 because it reaches a higher voltage, causing more current. () Light bulb #2 because it has a higher current, which indicates greater resistance. OLight bulb #1 because the greater slope of the line indicates greater.resistance. Light #2 because the smalier slope of the line Indicates greater resistance.
