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.
if it's a 240v heater. 1500/240=6.25amps.
23.6 amps
Watts are amps x volts, so w/o the volts the question can't be answered. At 100 volts it'd be 15 amps.
Amps = Watts / (Volts x Power Factor). Now a hair dryer has a motor and a resistive heater so if we assume a PF = .8 the answer is: 1500 / 20 = 75 amps. Since it is unlikely that you have a 75 amp hair dryer you must mean 125 volts. The answer for that would be 1500 / 100 = 15 amps which is still high, but believable. If we assume a Power Factor of 1 and ignore the motor contribution to Power Factor we have 1500 / 125 = 12 amps.
It all depends on the supply voltage. In the UK the supply voltage is 240V therefore the amps would be 1500w/240v = 6.25A. In the USA (with a supply of 110v) the amps would be 1500w/110v = 13.64A. All you need to remember is the formula 'amps = watts/voltage'
A 1500 Watt heating element about 1500/110 or 13.64 Amperes from a 110V service. It is assumed the heating element is made from a resistive wire.
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

"2kw fire" if this refers to an electric fireplace then you also need to know the voltage that is used. 1Kw = 1000 watts. Watts = Amps x Volts. Amps = Watts/ Volts. Amps = 2000/Volts.

Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.
The equation you are looking for is I = W/E. Amps = Watts/Volts.
Watts or Amps? Amps would be the alternator, don't know where you would find watts. Volts X Amps = Watts, for example 12 Volts X 55 Amp Alternator = 660 Watts

Those units describe different types of quantities, and the question is something likeasking "How many hours are in 15 gallons ?".When an electric current is consuming or dissipating 1,500 watts of power as it flowsfrom one point to another, then the number of amps of current is(1,500) divided by (the voltage between the two points) .
volts x amps = watts so 1500watts/12.8volts=117amps
