Question
In a complex circuit, three colored wires (red, green, andblue) are joined together inside a mysterious black box. Anammeter, a device that measures the rate of charge flow (current),shows you that charge enters the box at 3 coulombs per secondthrough the red wire and leaves the box at 2 coulombs per secondthrough the green wire. There is no buildup of charge inside thebox. After 10 seconds has elapsed, how much charge has flowed outof the box through the blue wire?In a complex circuit, three colored wires (red, green, andblue) are joined together inside a mysterious black box.

Explanation / Answer
As there is no buildup of charge , So total charge getting inside the box = charge going out of thebox . So charge going from blue wire+charge going from greenwire =charge entering from red wire charge going from blue wire + 2 C/s = 3 C/s So charge going from blue wire=1 C/s = 1 A Also total charge = current * time Here time = 10 second Putting the value Charge = 1 * 10 =10 C
