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:

Correct option is D

The correct answer is (d) $$I = \frac{Q}{t}$$

Explanation:

Electric current (I) is defined as the rate of flow of charge (Q) per unit time (t).

Mathematically, it is given by:

                                       $$I = \frac{Q}{t}$$​​

where:

• I = Electric current (Ampere, A)
• Q = Charge (Coulombs, C)
• t = Time (Seconds, s)

Unit of Current: 1 Ampere = 1 Coulomb/1 second (A = C/s).

Thus, the correct relation is I = \frac{Q}{t}​, making option D the correct answer.

Information Booster:

• Charge (Q) is measured in Coulombs (C).
• 1 Coulomb is the charge carried by 6.242 × 10¹⁸ electrons.
• The direction of the current is opposite to the flow of electrons.

Current types:

• Direct Current (DC) → Flows in one direction (e.g., batteries).
• Alternating Current (AC) → Changes direction periodically (e.g., household electricity).
