A 240-volt heater draws 18 amperes. What wattage is the load using?
Correct Answer
D) 4,320 watts.
Watts equal volts times amperes: 240 x 18 = 4,320 watts.
Why This Is the Correct Answer
Watts equal volts times amperes: 240 x 18 = 4,320 watts.
Why the Other Options Are Wrong
Option A: 3,240 watts.
3,240 watts. is below the supported result for electrical load calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 3,840 watts.
3,840 watts. is below the supported result for electrical load calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 4,080 watts.
4,080 watts. is below the supported result for electrical load calculation; it likely omits allowance, conversion, coverage, or final round-up.
Memory Technique
Measure to controlling, adjust for volts, then let Checking Electric 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 load calculation concepts; know the rule or calculation trigger without relying on exam-room lookup.
