Direct current (DC) is a steady flow of electric charge in a single direction. For DC circuits, the formula to convert volts to watts is straightforward: Watts (W) = Volts (V) × Amps (A) For instance, a DC system operating at 12 volts and drawing 2 amperes will require 24 watts o...
and I is the current in amperes. Power can also be expressed in volt-amperes and horsepower (HP), with the latter often used in everyday engines such as those in motor vehicles. 1 HP is equal to 746 watts.
The resistance R is equal to square of 5 volts divided by 2 watts, which is equal to 12.5 ohms.R = (5V)2 / 2W = 12.5ΩHow to convert ohms to volts ►See alsoHow to convert ohms to volts Electric current Volts Amperes Electrical calculations...
How Do You Calculate Amps Without Watts? In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 120V) and the resistance (ohms), you won’t be able toconvert watts to amps, but you can calculate the amperage of the device....
Sstands forapparent power; the very thing that is measured is Volt-Amperes (VA). Essentially, you might have already figured out thatVolt-Ampere is equivalent to a Watt(1 W = 1 A*V = 1 AV). Using this formula, we have prepared a calculator to convert kVA into amps. Here’s the ...
To calculate output voltage from a circuit, use Ohm's law. Voltage is measured in volts, current is measured in amps and the resistance is measured in ohms. The formula needed is V = I x R. You can use this formula in both parallel and series circuits.

How to convert kW to kVA with a formula If there is a current of 10 amperes in a circuit for 10 minutes, what quantity of electric charge flows in through the circuit? Does current change in a series circuit? What is the formula to convert watts to amps? How is current divided in ...
P (watts) = El = 3 X 0.1 = 0.3 W Suppose the voltage is 117 V, and the current is 855 mA. To calculate the power, we must convert the current into amperes; 855 mA = 855/1000 = 0.855 A. Then we have: P (watts) = 117 X 0.855 = 100 W ...
The 3.3 and 5 volts are typically used by digital circuits, while the 12 volt is used to run motors in disk drives and fans. The main specification of a power supply is in watts. A watt is the product of the voltage in volts and the current in amperes or amps. If you have been ...
