An offshore wind farm in the North Sea transmits electrical energy to the mainland grid via a High Voltage Direct Current (HVDC) link.
During a period of high winds, the wind farm transfers 5.85×1012 J5.85 \times 10^{12}\text{ J}5.85×1012 J of electrical energy.
The operating potential difference of the HVDC transmission line is 450 kV450\text{ kV}450 kV.
Calculate the total charge flow through the transmission line during this period.
Give your answer in standard form to 3 significant figures.
