WebApr 12, 2024 · A power of 100kW at a potential difference of 10kV is transmitted to a load resistor through cables of total resistance 5ohms. What is the power loss in the cables? The two equations for power that I know are I^2R and V^2/R. However, using the former with I given by 100kW/10kV and subbing this into equation above gives 500W (which is correct ...
