How many watts equals one AMP at 400 volts?
This question cannot be answered without knowing the voltage. Watts=Volts x Amps In the United States mains voltage (what you get in your house) is 120 Volts, so 120 x 400 = 48,000 Watts In Europe mains voltage is 230 Volts, so 230 x 400 = 92,000 Watts
How many amps equals 400 watts?
Watts = Amps x Volts x Power Factor. Power Factor = 1 for resistive loads and gets smaller for inductive loads like motors. Assuming home voltage of 120 Volts and a PF = 1 your answer is 400/120 = 3.33 amps.
How can you calculate the capacity in megawatts of a 400 kv power line?
You have to know the current carring capacity of the line and the power factor to make the calculation. Watts = Amps x Volts x p.f If p.f is unity, then watt = Amps x Volts
Does 50 amps rated at 240 volts equal 100 amps rated at 120 volts?
When you multiply amps x volts the product is watts. Using this formula W = Amps x Volts should give you your answer.
Watts equal to volt ampere?
Only when the load is purely resistive.

4 volts is a many 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.

How do you find out amps?
Volts x Amps = Watts

Only when the load is purely resistive.
How many watts in 40 amps?
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
How do you use ohm's law to determine the current flowing through a 45 ohm resistor at 1.4 amps?
The current is 1.4 amps, as already stated. The voltage is 45 x 1.4 volts.
Amps to watts?
Watts = Amps x Volts Amps = Watts / Volts you only need to know two of the three to work out the other so 230 volts at 10 amps gives 2300 Watts (2.3 kW) 2.3kW at 230 volts draws 10 Amps
How many amps per phase will a 45 Kw 380 volt unit use?
The equation that you are looking for is; amps when kilowatts are known. kW x 1000/1.73 x Volts x pf.45 x 1000 = 45,000/208 x 1.73 x pf. Power factor to use will be .9. 45000/ 324 = 139 amps.
What is the formula for calculating the full current load of a 400 watt light?
Assuming an incandescent bulb and a 120 volt supply the formula is Watts = Volts x Amps x Power Factor where PF = 1 for resistive load. Amps = 400 / 120.
