A 240-volt heater draws 18 amperes. What is the operating wattage?
Correct Answer
A) 4,320 watts.
Watts equal volts times amperes: 240 volts times 18 amperes equals 4,320 watts.
Why This Is the Correct Answer
Watts equal volts times amperes: 240 volts times 18 amperes equals 4,320 watts.
Why the Other Options Are Wrong
Option B: 2,400 watts.
2,400 watts. is below the supported result for electrical load calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 3,600 watts.
3,600 watts. is below the supported result for electrical load calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 5,760 watts.
5,760 watts. is above the supported result for electrical load calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.

Measure to controlling, adjust for volts, then let Checking Note set the finish line.
Reference Hint
Study anchor (closed-book): memorize Electrical load calculation from California Electrical Code, California Code of Regulations Title 24. / Title 24 California Electrical Code branch-circuit load concepts; know the rule or calculation trigger without relying on exam-room lookup.
