To determine how many amps a heater that operates on 120 volts and uses 3600 watts draws, you can use the formula that relates power (in watts), voltage (in volts), and current (in amps). The formula is:

[

P = V \times I

]

Where:

  • ( P ) is power in watts,

  • ( V ) is voltage in volts, and

  • ( I ) is current in amps.

You can rearrange this formula to solve for current:

[

I = \frac{P}{V}

]

Substituting the known values into the formula gives:

[

I = \frac{3600 , \text{watts}}{120 , \text{volts}}

]

Calculating this yields:

[

I = 30 , \text{amps}

]

This indicates that the heater draws 30 amps when operating at 120 volts and consuming 3600 watts. Understanding this relationship is vital in electrical applications, as it ensures that the circuit can handle the intended load without tripping breakers or causing safety hazards. By confirming that 30 amps is indeed the correct answer, it reflects the application of basic electrical
