A 2,000-watt heater draws 8 amps. What is its rated voltage?

To determine the rated voltage of a 2,000-watt heater that draws 8 amps, you can use the formula for electrical power:

Power (watts) = Voltage (volts) × Current (amps).

In this case, you need to rearrange the formula to solve for voltage:

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

Substituting the given values:

Voltage = 2000 watts / 8 amps = 250 volts.

This calculation shows that the rated voltage of the heater is 250 volts, which aligns with the correct answer. Understanding this relationship between power, voltage, and current is fundamental in electrical studies, as it helps to ascertain the operational parameters of various devices.
