Since power = voltage * current

we have current=power/voltage so 3500 watts/230 volts = about 15.218 amperes in a heater using a resistance to generate heat. This should be valid even though the "230 vac" indicates that it is an AC circuit and not a DC circuit.

If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?

Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous


What is the number of AMPS for a 240V 2400 watt water heater?

Watts = Amps x Volts for a resistive load like a water heater.


How many amperes use an electric heater?

The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).


What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?

To calculate the amperage draw, you can use the formula P = V x I, where P is the power in watts, V is the voltage in volts, and I is the current in amps. Given that the power is 1200 watts and voltage is 120 volts, you can rearrange the formula to solve for current. Therefore, I = P / V, so the amperage draw of the heater would be 10 amps.


A 2000 watt heater connected to a 120 volt circuit will draw a current of?

Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps


How many amps will a 400 watt heater cartrige draw at 240 volts?

The formula you are looking for is I = W/E.


How many amps does a block heater draw?

To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.


You were given aload 2500 watts how much it draw amps?

To calculate the amperage draw, you need to know the voltage of the circuit where the 2500 watts appliance will be used. You can use the formula: Amps = Watts / Volts. For example, if it is a 120V circuit, the amperage draw would be 2500 watts / 120 volts = 20.83 amps.


How many amps does a 2000 watt heater draw at 240 volts?

Amps * Volts = Watts So, Watts / Volts = Amps 2000 / 240 = 8.333 Amps You should run the circuit on a two pole 15 Amp breaker, using 14 AWG, 2 conductor (plus ground) wire, just so you have a little safety factor in the circuit size.


10kw heater at 220V draws how many amps?

45-50 amps. But your overcurrent protection and wire must be designed for 125% of load so the max overcurrent protection is 55 amps or 60


Are electric baseboard heaters efficient?

Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps


How many watts or amps draw on a GE water heater model se50m12aa01?

The GE water heater SE50M12AA01 is a 5500 watts or 5.5 Kilowatts water tank. The amperage on such a tank is I = W/E. Amps = Watts/Volts. Since most hot water tanks in North America use a voltage of 240, the amps will be 22.9 amps. It must be fed with a #10 conductor from a 30 amp breaker.
