Electrician's Licensing Practice Exam

If you have 1,800 watts for baseboard heat at 240V, how many amps does it draw?

1. 5 amps

2. 6.25 amps

3. 7.5 amps

4. 8 amps

The correct answer is: 7.5 amps

To determine how many amps a baseboard heater rated at 1,800 watts draws at 240 volts, you can use the formula: Amps (A) = Watts (W) / Volts (V) In this case, you would calculate it as follows: Amps = 1,800 watts / 240 volts Amps = 7.5 amps This calculation shows that the heater operates at 7.5 amps when powered by 240 volts. Understanding the relationship between watts, volts, and amps is crucial for electric work because it ensures that circuits are properly rated and can handle the electrical load safely without risking overload or potential hazards. Therefore, when you have a load of 1,800 watts at 240 volts, it will indeed draw 7.5 amps, making that the correct answer.
