Just multiply.
(Note, this assumes no phase difference.)

How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
The differene between amps and watts?
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
How do you work out resistance?
Using Ohms law, the resistance can be calculated by using the following formulas. R = Watts/Amps (squared). R = Volts (squared)/Watts. R = Volts/Amps.
How many volts in 6VA?
There are zero volts in 6 VA. The VA stands for Volt Amps. VA for all intents and purposes is the same as watts. You need to state an amperage to find the voltage. Volts = Watts/Amps.
What is the resistance of a 40 watt bulb?
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
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.
How many amps are in 2000 watts using 110 volts?
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.
How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
What if the input power is 208 volts line to line two phase 8 amps to a heating element vs 110 volts 8 amps to a heating element How is watts calculated?
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
How many amps times volts equals 13.75 watts?
You would have to know either the value of Volts or Amps to calculate that. watts = volts x amps Without either of those values nothing can be done.
How do you calculate the current?
If the wattage of a load is known then the current can be calculated. Watts equals amps times volts. You would use the following formula, Amps = Watts/Volts.
HoW many amp is 300 watts?
As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts
How many watts is equal to 4.3 amps at 230 volts?
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
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 many amps with 70 watts 13.8 Volts dc?
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
250 watts is how many amps?
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.
How many volts in 12 mega watts?
Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
