A subsea High Voltage Direct Current (HVDC) transmission link is used to transfer electrical energy between two national grids.
On a day of peak wind-power production, the link transfers 1.38 × 1013 J of electrical energy across the channel.
The potential difference maintained across the transmission line is 460 kV460\text{ kV}460 kV.
Calculate the total charge flow through the link during this transfer.
Give your answer to 3 significant figures.
