For two electric heaters each drawing 6.25 amps at 240v, what is their total BTU output?

To determine the total BTU output of the two electric heaters, we first need to calculate the power consumed by each heater in watts and then convert that power to BTUs.

Each heater draws 6.25 amps at 240 volts, so we can calculate the power consumed by one heater using the formula:

Power (Watts) = Voltage (Volts) × Current (Amps)

For a single heater:

Power = 240 volts × 6.25 amps = 1500 watts

Since there are two heaters, the total power consumption can be calculated by multiplying the power of one heater by two:

Total Power = 1500 watts × 2 = 3000 watts

Next, we need to convert watts to BTUs. The conversion factor is approximately:

1 watt = 3.412 BTUs

To find the total BTUs for the two heaters, we multiply the total power in watts by the conversion factor:

Total BTUs = 3000 watts × 3.412 BTUs/watt = 10,236 BTUs

When we round this value to the nearest whole number, we get approximately 10,239 BTUs. This matches the provided choice, confirming that the answer is indeed accurate.
