What is Wire Loss?
Wire loss, also known as power loss in electrical conductors, is the energy lost due to the resistance of the wire when current flows through it. This is a common phenomenon in all electrical systems and is calculated using Ohm’s Law: P=I2×RP = I^2 \times RP=I2×R
Where:
- PPP = Power loss in watts (W)
- III = Current flowing through the wire in amperes (A)
- RRR = Resistance of the wire in ohms (Ω)
Minimizing wire loss is essential for optimizing energy efficiency, reducing costs, and improving system longevity.
How to Use the Wire Loss Calculator
Using the Wire Loss Calculator is simple, even if you are not a professional electrician. Follow these steps:
- Enter the Current (A):
Input the current flowing through the wire in amperes. This value can usually be found from your circuit specifications or measured using a multimeter. - Enter the Wire Resistance (Ω):
Provide the resistance of the wire in ohms. Wire resistance depends on the material (copper, aluminum), wire gauge, and length. - Click “Calculate”:
Press the Calculate button. The calculator instantly computes the power loss in your wire and displays the result. - View Results:
The power loss will appear in watts. This value helps you understand how much energy is being wasted due to the wire’s resistance. - Reset Values (Optional):

Example Calculation
Let’s see a practical example to understand how the calculator works:
Scenario:
You have a wire with a resistance of 2 ohms, and the current flowing through it is 3 amperes.
Calculation using the formula: P=I2×R=32×2=9×2=18 wattsP = I^2 \times R = 3^2 \times 2 = 9 \times 2 = 18 \text{ watts}P=I2×R=32×2=9×2=18 watts
Using the Wire Loss Calculator, you simply enter 3 for current and 2 for resistance, click Calculate, and it will show 18 W as the power loss.
This tool is perfect for engineers designing electrical systems, electricians troubleshooting circuits, or homeowners checking the efficiency of household wiring.
