This tool will calculate the electrical power dissipated by a copper conductor based on its resistance and the current passing through it.
How to Use the Copper Power Loss Calculator
This calculator allows you to determine the power loss in a copper conductor based on several parameters.
- Voltage (V): Input the voltage applied across the conductor.
- Current (A): Input the current flowing through the conductor.
- Length (m): Input the length of the conductor in meters.
- Resistivity (ohm*meter): Input the resistivity of the material. This is defaulted to copper’s resistivity (1.68e-8 ohm*meter).
- Cross Sectional Area (sq.mm): Input the cross-sectional area of the conductor in square millimeters.
Once you have filled all the values, click the “Calculate” button to get the power loss in watts (W).
How It Calculates
The calculator uses the formula:
Power Loss (W) = Current² (A) * Resistance (Ω)
Where the resistance is calculated as:
Resistance (Ω) = (Resistivity (Ω*m) * Length (m)) / Cross Sectional Area (m²)
Limitations
This calculator assumes uniform properties and conditions along the length of the conductor. Variations in temperature, impurities in the material, and other real-world factors can affect the accuracy of the calculated power loss. The default resistivity value is for copper and should be changed if you are using another material.
Use Cases for This Calculator
Calculating Copper Power Consumption
To calculate the power consumption for copper appliances, enter the wattage of each device you want to power with copper cable. The calculator will sum up the total power consumption. It’s helpful for ensuring your copper cables can handle the electricity load without overheating.
