The correct relation between charge(Q) following through a conductor, time(t) for which the charge follows and the current (I) following through the conductor is:

The Correct answer is I = Q/t.

Key Points

• The relation I = Q/t is derived from the definition of electric current.
• Electric current is defined as the rate of flow of electric charge through a conductor.
• Here, I represents the current, Q is the total electric charge, and t is the time taken for the charge to flow.
• The formula indicates that the current is directly proportional to the amount of charge and inversely proportional to the time.
• The SI unit of current is the ampere (A), charge is measured in coulombs (C), and time in seconds (s).
• This fundamental equation is widely used in various applications of electricity and electronics.
• For example, it helps in calculating the current flowing through a circuit if the charge and time are known.
• The concept is crucial for understanding topics related to Ohm's law, circuits, and power calculations in electrical engineering.
