A=w/v
a=2000/110
a= 18w
To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
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.
To obtain the amperage from 2000 watts the voltage is needed. I = W/E. Amps = Watts/Volts.
When they give you WATTS the also give you VOLTS. Using some very simple math you can then figure out AMPS. WATTS = Amps x Volts
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.

"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.
When they give you WATTS the also give you VOLTS. Using some very simple math you can then figure out AMPS. WATTS = Amps x Volts
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
Using Ohms law, the resistance can be calculated by using the following formulas. R = Watts/Amps (squared). R = Volts (squared)/Watts. R = Volts/Amps.
Watts is volts times amps, so 12 x 30 = 360 watts
