What is the load from a 4-kilowatt electric heater operating at 240 volts?

To determine the load from a 4-kilowatt electric heater operating at 240 volts, we can use the formula for electrical power, which relates power (in watts), voltage (in volts), and current (in amperes). The formula is given as:

Power (P) = Voltage (V) × Current (I)

Rearranging this to find the current gives:

Current (I) = Power (P) / Voltage (V)

Plugging in the values:

• Power (P) = 4,000 watts (since 1 kilowatt = 1,000 watts, 4 kilowatts equals 4,000 watts)

• Voltage (V) = 240 volts

Now we can calculate the current:

I = 4,000 watts / 240 volts

I = 16.67 A

This calculation indicates that the load current drawn by the heater is 16.67 amperes. Therefore, the correct choice is the one that aligns with this calculation.

The reasoning behind the other options not matching this answer rests in the arithmetic of the formula used. Any current value higher than 16.67 A indicates an incorrect application of the power formula with the given voltage, leading to overestimation
