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.
Which equation should be used to find current when volts and watts is given to you?
You can use the formula I = P/V, where I is the current in amperes, P is the power in watts, and V is the voltage in volts.
How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?
The power consumed by the light bulb can be calculated using the formula P = I * V, where P is power in watts, I is current in amperes, and V is voltage in volts. In this case, the power consumed is 1.2 amperes * 12 volts = 14.4 watts.
How many watts makes 110 volts?
To find the number of watts when given volts, use the formula: Power (in watts) = Voltage (in volts) x Current (in amperes). Without knowing the current (amperes) in this case, the question cannot be answered.
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.
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 many amps would 2600watts use 240v 50hertz?
To find the amperage, use the formula: Watts = Volts x Amps. Given 2600 watts and 240 volts, the amperage would be calculated as 2600 watts / 240 volts = 10.83 amps.
How do you calculate watts volts and amperes in air conditioner?
To calculate the power consumption of an air conditioner in watts, you multiply the voltage (V) by the current (I) in amperes. The formula is: Power (W) = Voltage (V) x Current (A). You can usually find the voltage and amperage ratings on the air conditioner's label or in its manual.
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 much current does 60 watts Operated at 480 volts have?
To calculate the current, we can use the formula Power (watts) = Voltage (volts) * Current (amps). Plugging in the values given, we get 60 watts = 480 volts * Current. Solving for Current, we find Current = 60 watts / 480 volts = 0.125 amps.
How many watts are in 5 volts?
The wattage of a system depends on the current (in amperes) flowing through it as well as the voltage. If the current is known, you can use the formula Watts = Volts x Amperes to calculate the wattage.
