Question 218Electricity/Electronics - QMED70% to pass
What is the wattage of a heating element drawing a current of 30 amperes, at 120 volts?
AI Explanation
The correct answer is D) 3600 watts.
The formula for calculating the power (in watts) of an electrical device is: Power (watts) = Voltage (volts) x Current (amperes). In this case, the voltage is 120 volts and the current is 30 amperes. Plugging these values into the formula, we get: Power = 120 volts x 30 amperes = 3600 watts.
The other options are incorrect because they do not correctly apply the power formula. Option A) 30 watts is too low, Option B) 99.97 watts is incorrect, and Option C) 360 watts is also incorrect.
