Question

In a conductor, 10 ampere of current is flowing. What will be the amount of charge flowing in 2 seconds corresponding to it?

• A. 10 coulomb
• B. 5 coulomb
• C. 20 coulomb
• D. 25 coulomb

Hint:

Use the relation \( Q = I \times t \). Always ensure the units are consistent — current in amperes, time in seconds, charge in coulombs.

Answer 1

The Correct Option is C

Step 1: Recall the formula for electric current.
Electric current (\( I \)) is defined as the rate of flow of electric charge (\( Q \)): \[ I = \frac{Q}{t} \] or rearranging, \[ Q = I \times t \] Step 2: Substitute the given values.
Given, \( I = 10 \, \text{A} \) and \( t = 2 \, \text{s} \): \[ Q = 10 \times 2 = 20 \, \text{Coulomb} \] Step 3: Conclusion.
Therefore, the total charge passing through the conductor in 2 seconds is 20 coulomb.
