The net charge that passes through any point in the circuit during a thirty second interval is given by:$$Q = It$$where:* Q is the charge in coulombs* I is the current in amperes* t is the time in secondsIn this problem, we have:* I = 3.5 A* t = 30 sSo, the net charge that passes through any point in the circuit during a thirty second interval is:$$Q = (3.5 A)(30 s) = 105 C$$Therefore, the correct answer is A.

A 35-A Current Is Maintained in a Simple Circuit with a a Total
