[Help] Power Loss in power cable

Click For Summary
A factory aiming for carbon neutrality has installed a wind turbine 1 km away and requires 2 km of copper wire to connect it. The resistance of the wire is 1.2 Ω, and the turbine generates 12V DC, needing to supply 1 kW of power. Calculations show that transmitting at 12V results in excessive voltage drop, making it impractical, while using 230V allows for feasible current levels and power delivery. The discussion emphasizes the importance of applying Kirchhoff's Voltage Law (KVL) to set up equations for power loss and efficiency. Ultimately, the analysis indicates that 230V transmission is the more efficient option for delivering power to the factory.

I think you get the picture :biggrin:

Now that you've identified the practical choice, you should have all the information required to complete the problem sections.

Thank you so much.
I feel like this would have been next to impossible without your guidance
:oldbiggrin:
