An industrial induction furnace uses high-power electromagnetic coils to melt metal scrap.
Write down the equation which links charge flow (QQQ), current (III), and time (ttt).
During a specific heating cycle, the furnace system delivers a steady current of 8,500 A8,500\text{ A}8,500 A to the coils for a duration of 14 minutes14\text{ minutes}14 minutes. Calculate the charge flow during this cycle.
State the correct SI unit for charge flow from the following choices:
