How many amps is 1500 watts at 120V?

1500W ÷ 120V = 12.5 amps. A 1500-watt space heater on a 120V circuit draws 12.5 amps, which is within the 80% limit of a 15-amp circuit (12A max continuous).

How do I convert watts to amps?

Divide watts by volts: Amps = Watts ÷ Volts. For example, a 2400W appliance on 240V draws 10 amps.

How many watts is 15 amps at 120V?

15 amps × 120V = 1800 watts. With the NEC 80% continuous load rule, a 15-amp circuit can safely supply 1440 watts continuously.

What is the difference between watts and volt-amps (VA)?

Watts measure real power (actual work done). VA measures apparent power (voltage × current). They are equal for purely resistive loads but differ for inductive loads due to power factor.

How many amps does a 5000 watt air conditioner draw?

A 5000W air conditioner at 240V draws 20.8 amps, requiring a 30-amp breaker. At 120V, it would draw 41.7 amps, which is why large AC units use 240V.
