A conductor carries a current of 5 A for 4 min. What is the number of electrons that passes through the cross-sectional area of the conductor?
Current is a physical quantity which determines the rate of flow of charge through a conductor.
Current flows in a conductor when energy is supplied to the electrons either by maintaining a potential difference or by the application of some external energy.
Answer and Explanation:
Current in the conductor is i = 5 A.
Time of flow of current is t = 4 min = 240 s.
The relation between the charge Q passing through the...
