volts x amps = watts
so 1500watts/12.8volts=117amps
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
124.3 amps. If you have one on a vehicle, for example a winch, use no less tha 00g cable. That is a LOT of power, and an ordinary alternator can't handle that.
It depends on what kind of amp it is. Is it an audio amp or an rf amp . . A 3 kW audio amp would draw about 300 watts on average at most, so with a good reservoir capacitor the supply current would be 0.2 amps. A 3 kW rf amp for AM radio would draw about 4500 watts so the supply current would be 3 amps.
By the definition of power which is (p)=IV, if a 1500 watt Electric Fireplace is plugged in a 220v AC source, the expected current will be (I)=P/v. ie 1500/220=6.8A This is when the power loss due to cable resistance is neglected.
About 0.6 amps for a 12v 21w bulb
A deep freezer can draw between 6 to 8 times its running amps on start-up, depending on the model and size of the freezer. For example, if a freezer runs at 6 amps, it could draw between 36 to 48 amps when starting up.
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.
Presuming single phase and 1500 rpm. Normal running current would nearly 10 Amps but varies considerably. A real cheap one running at 3000/3600 rpm could exceed 12 amps. At 240 volt, all should be run off 15 Amp line.
100 amps
An electrical device may draw amps, but there is not a device that equates to amps. Amperes are the measure of current flow in a circuit.
Each 32-watt bulb in a 48-inch fluorescent light typically draws around 0.27 amps. Therefore, a two-bulb setup would draw approximately 0.54 amps in total.
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).
