How much power does an electric heater drawing 5 amps at 110 volts consume?

To determine the power consumed by an electric heater, you can use the formula for electrical power, which is calculated as the product of current (in amps) and voltage (in volts). The formula is:

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

In this case, the heater draws a current of 5 amps at a voltage of 110 volts. Substituting these values into the formula gives:

Power = 5 amps × 110 volts = 550 watts

Therefore, the amount of power consumed by the electric heater is 550 watts. This aligns perfectly with the choice that states 550 watts, confirming it as the correct answer.

Understanding this concept of basic electrical power calculations is significant in power engineering, as it allows engineers to determine the power requirements of various electrical devices accurately, ensuring that the systems designed can handle the necessary load efficiently.
