The label on a ceiling lighting fixture warns you to use a lightbulb of 60 watts or less. The voltage to the lightbulb is 120 volts. An intern calculated how much amperage a bulb of the maximum allowed wattage will draw. You are checking her work, shown below. If there is an error, what is the first step that has an error, and why is it an error?

Step 1 volts × amps = watts write down formula
Step 2 120 × ? = 60 fill in what is known
Step 3
It looks like 0.5 will work

120 × 0.5 = 60

check
Step 4 amps = 0.5
Step 1, because the formula should be amps = watts ÷ volts.
Step 2, because the question mark should be by itself on the right side of the equation.
Step 3, because you can’t just guess at a solution.
Step 4, because the answer in the previous step was 60.
There is no error
