Wrong question. I assume that this pertains to a car and not a house. All modern cars run on a 12-volt system. So what I think you meant to ask is "how many AMPS in 90 watts at 12 volts?". Watts divided by volts equals amps, so 90 watts divided by 12 volts equals 7.5 amps. If you are trying to wire in a car stereo amp, better go with a 10 amp fuse.
volts times amps = watts
Watts and Volts are two distinct types of measurement.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
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.
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
To determine how many amps are in 115 volts, you need to know the power (in watts) being used. The relationship between volts, amps, and watts is given by the formula: Watts = Volts × Amps. Therefore, to find the amps, you can rearrange the formula: Amps = Watts / Volts. For example, if you have a device that uses 1150 watts, you would have 10 amps at 115 volts (1150 watts ÷ 115 volts = 10 amps).
watts = volts x amps, example-2 watts=2 volts x 1 amp, example- 2 watts=120 volts x .60 amp.
41.666 amps. Divide watts by 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.
It depends on how many amperes there are. If you have 1 amperes, then you get 260 watts. If you have 260 amperes, then you have 67,600 watts. If you have 0.001 amperes, then you have 0.26 watts. Its just watts = volts times amperes. Of course, the limiting factor is the available power behind the 260 volts, but you did not say anything about that.
You can't convert volts to amperes. Those are quite different units; that would be like converting, say, meters to seconds.
