A small factory has decided to go Carbon neutral and has installed its own wind turbine. The wind turbine is installed on land belonging to the factory 1 km away. The factory owner needs 2km of copper wire of diameter 3mm to connect the turbine to the factory. The resistance of the cable is 1.2 Ω. a) What is the resistivity of the wire? The turbine generates 12V dc electricity and needs to supply the factory with 1kW of power. The factory owner has the choice inverting the supply to 230V or transmitting it at 12V. By calculating: b) The current that passes along the cables if they are to deliver 1kW of power to the factory c) The power that would be lost in the connecting wires d) The total power that must be generated e) The efficiency of the transmission For both voltages decide which is a more efficient mode of transmission? For: Resistivity p= RA/L I got 4.242x10^-9 ohmmeters to 4 s.f. not sure how to implement the Power loss Formulas: P = IV = I^2R = V^2/R Would I use V=IR to find current and Voltage drop and the add to the power loss formulas or use I=p/v for current and use the initial voltages? How do I go about finding the total power generated to deliver the 1KW of power to the destination? would it be a case of simple addition or is there a formula for this?
