Look at it this way... 1 Watt = 1 Volt x 1 Amp Without knowing amperage, your question is unanswerable.


Example - your 110 Volt house wiring can power 40w or 60w or 100w or ... w light. however they all have different currents.

The formula you are looking for is W = I x E. W = A x V.

To answer this question the amps or mA of the adapter must be stated. Volts = Watts/Amps.

Watts are the product of amps times volts. Therefore 175 watts is zero volts. Without an amperage the voltage cannot be calculated. E = W/I, Volts = Watts/Amps.

Watts = amp x volts. As you can see by the formula you have parameters missing. You need a number for the voltage or you need amperage to give you the voltage.

How do you convert watts into amperes?

To convert watts into amperes you divide the circuit voltage into the watts. Amps = Watts/Volts. <<>> Converting Watts to Amps The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts For example 12 watts/12 volts = 1 amp Converting Amps to Watts The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts For example 1 amp * 110 volts = 110 watts Converting Watts to Volts The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts Converting Volts to Watts The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts For example 1.5 amps * 12 volts = 18 watts Converting Volts to Amps at fixed wattage The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Explanation Amps are how many electrons flow past a certain point per second. Volts is a measure of how much force that each electron is under. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage). But if you restrict the end of the hose, letting the pressure build up, the water can have more power (like watts), even though it is still only one gallon a minute. In fact the power can grow enormous as the pressure builds, to the point that a water knife can cut a sheet of glass. In the same manner as the voltage is increased a small amount of current can turn into a lot of watts.


How do you solve for current using volts and watts in a problem?

Amperes measure the rate of flow of electricity in a conductor Volts measure electrical pressure Watts measure the amount of energy or work that can be done by Amperes and Volts Relationship: Work = Pressure x Flow or Watts = Volts x Amperes When you know two variables you can calculate the other Formulas - This formula referred to as the West Virginia Formula (W - VA)Watts = Volts x Amps Volts = Watts / Amps Amps - Watts / Volts Refer to link below for more information


How much current must flow to carry 240 watts at 120 volts?

240 watts at 120 volts requires 2 amperes. Power = voltage * current


Which is higher in energy Watts or volts?

Watts = Volts X Amps. Thus watts and volts are related but neither is higher in energy. Energy is measured as power times times, in other words watts times seconds (called Joules) or kilowatt-hours (called Units).


2kw fire What amperage used?

"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.

How much is 2 watts?

There are no "watts" in 2.5 volts. Wattage is the result when you multiply volts times amps. You cannot answer the question with only one quantity (in this case 2.5 volts). If you have 1 amp and 2.5 volts, they you would have 2.5 watts. If you had 2 amps and 2.5 volts, they you would have 5 watts. The formula is Volts X Amps = Watts.


How many watts are in 30 volts?
