A soldering iron rated at 480 watts on a 240 volt supply draws how much current?
Pick an answer
Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 103 (Electronics Information): 2 amperes

Current equals power divided by voltage, so 480 / 240 = 2 amperes. Multiplying the two figures instead gives a meaningless result far too large.
