If the wattage of a 120V AC heating element is lowered to 1200 Watts, what is its amperage draw?

5.0 amps
10.0 amps
15.0 amps
20.0 amps

The correct answer is: 10.0 amps

To determine the amperage draw of a heating element when the wattage and voltage are known, you can use the formula derived from Ohm's Law, which is: Amperage (A) = Wattage (W) / Voltage (V). In this case, the wattage of the heating element is 1200 Watts, and the voltage is 120 Volts. Using the formula: Amperage = 1200 Watts / 120 Volts = 10 Amps. So the correct answer is that the amperage draw is 10.0 amps, which aligns with the provided answer. Understanding this relationship between wattage, voltage, and amperage is crucial for RV technicians, as it helps in safely assessing electrical systems and components within recreational vehicles.
