How to Convert Watts to Amps. Converting watts to amps can be done using the Watt’s Law formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts.. Given this, to find amps given power and voltage use the following formula:
How to convert Watts to Amps or Amps to Watts or Volts to Watts. Basics. You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts or watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship ...
How to convert 15 amps to watts. ... You can calculate (but not convert) the watts from amps and volts: 15A to watts calculation with voltage of 12V DC. For DC power supply, watts are equal to amps times volts. watts = amps × volts. watts = 15A × 12V = 180W. 15A to watts calculation with voltage of 120V AC. For AC power supply, watts are ...
If you want to convert Watts to Amps in a DC system, divide the Watts by the Volts. For example, if you have a system running 500 Watts at 200 volts, then you have 2.5 Amps. To convert Watts to Amps in an AC system, read the circuit label or schematic to find the power factor.
First of all you also need to know about the amperage too.Then you do all the calculation through ohms law to get the appropriate solution. Assume that if you have 120 volts and an amperage of 10 amps, then you should multiply 120 by 10, then you get 1200 watts.
Calculate Watts from Volts and Amps If you want to convert watts to amps on your own, you can use this equation: Watts = Amps x Volts or W = A x V As long as you know two of the electrical ratings, you can calculate the missing info with simple math.
AC three phase watts to amps calculation Calculation with line to line voltage. The phase current I in amps (A) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage V L-L in volts (V):
Technically, you can't convert directly from watts to amps because each unit measures an intrinsically different aspect of electricity. However, watts, amps and volts are all related. So if you know any two of those elements, you can use an appropriate equation to find the third.
Convert amps to volts. How to Convert Volts to Amps. Voltage is the potential difference in an electrical circuit, measured in volts. It might be easier to think of it as the amount of force or pressure pushing electrons through a conductor.
The calculation for watts to amps is : Watts / Voltage = amps. 240 Volt example A 400 watt ballast plugged into ordinary house current (240v) would draw 1.67 amps. 120 Volt example A 400 watt ballast plugged into ordinary house current (120v) would draw 3.33 amps.
