I would assume you are speaking of AC circuits, and do not wish a long winded engineering primer.
The basic formulas to calculate all:
A=Amperes
V=Volts
W=Watts
AxV=W , W/V=A, W/A=V
So, to find Amps, divide voltage into the wattage A = W/V

How many watts are in 115 volt fridge?
The number of watts measures the power, and Ohm's laws requires us to know the current as well as the voltage to determine the power.P = i x eFor example, if the fridge draws 10 amps at 115 volts, the power is 1150 watts.AnswerThe answer is that it depends on the fridge. Look at the nameplate information for your particular fridge; that's where you will find your answer.
How do you find an endpoint if you are given the midpoint?
Given only the midpoint you cannot.
How do you find the area of a triangle if equations are given?
It depends on what equations are given.
How do you find the perimeter of a hexagon if the area is given?
In general you cannot find the perimeter of any shape if only the area is given.
How can you find a faction equivalent to a given fraction?
Multiply the given fraction by 1.
How many volts can you get from 260 watts?
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.
How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?
144 watts <<>> The formula to find watts is W = A x V. Watts =Amps x Volts.
How do you find watts when given volts and horsepower?
1 horse power=746watt
How you find ups watts?
It is expressed in Volt-Amperes not Watts.
How do you convert horse power into watts?
Divide by 745.7 the formula is watts over Current times volts so if you want to know how many amps you are using you would divide the volts into the watts that will give you the current(amps) needed to drive this device by the same token you can use the formula to find the volts by dividing the current into the watts. if two elements are known you can determine the unknown factor. if you know the amperes and the voltage you just multiply volts time amperes and you find the watts . confusing isn't it ? example 110 volts X 10 Ampere's 1,100 watts . so you would have about almost a horse and a half motor or device .
How many watts does 100 amps at 120 v?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
What is the formula to find watts?
There are several ways to find watts; volts x amps = watts or resistance (ohms) divided by amps squared or volts squared divided by amps. You can search for Ohm's Law to find examples of these different methods and sample calculations.
Can i use 10amp fuse for 1000 watts instant heater?
There are zero amps in 1000 watts. Watts are the product of amps x volts or I = W/E, watts divided by voltage. As you can see, that if no voltage is stated no amperage can be given. Once you find the voltage of the heater then use the following equation, Amps = Watts/Volts to find the current draw of the 1000 watt heater.
How do you find out amps?
Volts x Amps = Watts
How do you find ampes?
Volts x Amps = Watts
Where can you find 55watts on a Chevy prizm?
Watts or Amps? Amps would be the alternator, don't know where you would find watts. Volts X Amps = Watts, for example 12 Volts X 55 Amp Alternator = 660 Watts
How many watts in 0.8 amps?
There are zero watts related to 1.8 amps. Watts are the product of amps times volts. The equation that is used to find watts is Watts = Amps x Volts. Insert the circuit voltage into the equation and you will find the circuit's wattage load.
