Suppose that a lithium-ion cell having total charge capacity Q=10Q=10Ah is discharged at a rate of 1A for 30min. What is the net change in the cell's state of charge (in percent)? Round to the nearest percent. (Hint: I am looking for a signed answer — the answer is positive if the state of charge increases and it is negative if the state of charge decreases.)
