Enter the current and resistance into the calculator to determine the power in kilowatts. This calculator can also evaluate any of the variables given the others are known.
Ohms To Kilowatts Formula
The following formula is used to calculate power in kilowatts from resistance in ohms, given the current in amperes.
P = I^2 * R
Variables:
- P is the power in kilowatts (kW)
- I is the current in amperes (A)
- R is the resistance in ohms (Ω)
To calculate the power in kilowatts, square the current in amperes and multiply the result by the resistance in ohms. Note that this formula assumes that the current is constant and the circuit is DC. For AC circuits, additional factors such as phase angle and power factor would need to be considered.
What is Ohms To Kilowatts?
Ohms to Kilowatts is not a direct conversion as they are two different units measuring different aspects of electricity. Ohm is a unit of electrical resistance, indicating how much a material resists the flow of electric current. Kilowatt, on the other hand, is a unit of power, representing the rate of energy conversion or transfer. To relate these two, you would need additional information such as current or voltage, and use Ohm’s Law and the power calculation formula.
How to Calculate Ohms To Kilowatts?
The following steps outline how to calculate the Ohms To Kilowatts using the formula: P = I^2 * R.
- First, determine the current in amperes (I).
- Next, determine the resistance in ohms (R).
- Next, square the value of the current (I^2).
- Then, multiply the squared current by the resistance (I^2 * R).
- Finally, divide the result by 1000 to convert the power to kilowatts (P = I^2 * R / 1000).
- After inserting the variables and calculating the result, check your answer with the calculator above.
