A steady current is passing through a conductor of non-uniform cross-s...
Explanation:
When a steady current passes through a conductor, the net quantity of charge crossing any cross-section per second is indeed independent of the area of cross-section. Let's understand why this is the case.
1. Definition of Current:
Current (I) is defined as the rate of flow of charge. Mathematically, it is given by the equation:
I = Q/t
where I is the current, Q is the quantity of charge, and t is the time taken.
2. Steady Current:
In this scenario, we are dealing with a steady current. This means that the current is constant and does not change with time. Therefore, the net quantity of charge crossing any cross-section per second should also be constant.
3. Cross-sectional Area:
The cross-sectional area of a conductor refers to the area of the conductor when it is cut perpendicular to the direction of the current. In this case, the conductor has a non-uniform cross-section, meaning that the area varies along its length.
4. Quantity of Charge:
The quantity of charge crossing any cross-section per second can be calculated by multiplying the current with the time taken. As the current is constant in a steady current scenario, the quantity of charge crossing any cross-section per second should also be constant.
5. Independence of Area:
Since the quantity of charge crossing any cross-section per second is constant, it is independent of the area of cross-section. This means that even if the area of cross-section varies along the length of the conductor, the net quantity of charge crossing any cross-section per second remains the same.
Conclusion:
In summary, the net quantity of charge crossing any cross-section per second in a steady current is independent of the area of cross-section. This is because the current is constant in a steady current scenario, and the quantity of charge crossing any cross-section per second is determined solely by the current and the time taken.
