- Hello, I need help with question 15, the diagram is attached separately. Please and thankIf it takes 8.3 seconds for 2.5 Coulombs of charge to move through a wire, what is the current through the wire? If the voltage was 1.5 V (so 1.5 joules of energy per coulomb of electrons), then how much energy was used in those 8.3 seconds? Wait, if that is the total energy used, what was the rate of energy used, as in Joules per second? What is the name of that measurement, Joules per second (energy over time)?A copper transmission cable 34 km long and 19.5 cm in diameter carries a current of 11 A. How much electrical energy (in MJ) is dissipated as thermal energy in 9 hours? Note: = 1.72x10-8 m show the complete and organize solution and dont round off show the final asnwer in 4 decimal places if possible
