A current of 4 A flows around a circuit for 10 s. How much charge flows past a point in the circuit in this time ?
Charge flowing, Q=I×t=4 A×10 s=40 C
A current of 5 A flows through a circuit for 15 minutes. The amount of electric charge that flows through the circuit during this time equals __ C.
In how much time (in seconds) should a charge of 10 coulombs flow between two terminals of a circuit so as to maintain a constant current of 100 A?
