A motor draws 10 amps at 120 volts. What is the rate at which work is being done?

To determine the rate at which work is being done by the motor, you can use the formula for electrical power, which is calculated by multiplying the current (in amps) by the voltage (in volts). In this case, the motor draws 10 amps at 120 volts.

The calculation is as follows:

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

Using the values provided:

Power = 10 amps × 120 volts = 1200 watts

Since power is often expressed in kilowatts (kW) in electrical applications, you can convert watts to kilowatts by dividing by 1,000:

1200 watts ÷ 1000 = 1.2 kW

This result indicates that the motor is doing work at a rate of 1.2 kilowatts, which aligns with the choice identified. Understanding this relationship between current, voltage, and power is fundamental in electrical work, especially for linemen and those involved in electrical maintenance and installation.
