The kilowatt output of an electric heater with a 240 volt supply and a current draw of 50 amps is?

To determine the kilowatt output of an electric heater, you can use the formula for electrical power, which is calculated as follows:

Power (kW) = Voltage (V) × Current (A) / 1000

In this scenario, the heater operates at a voltage of 240 volts and draws a current of 50 amps. Plugging these values into the formula gives:

Power (kW) = 240 V × 50 A / 1000 = 12 kW

This calculation shows that the electric heater produces 12 kilowatts of power. Understanding this formula is crucial for evaluating electrical devices in terms of their power consumption and output. Having accurate measurements of both voltage and current is essential for calculating electrical power correctly.
