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 ?
What amount of time it will take to pass 1019 electrons through a point inside the circuit, if a constant current of 8 A is flowing in it?
How is the direction of electric current related to the direction of flow of electrons? Calculate the current in a circuit if 500C of charge passes through it in 10minutes.
