Uncategorized: Practice Problem & Solution

1. Across a metallic conductor of non-uniform cross section a constant potential difference is applied. The quantity which remains constant along the conductor is: (2015)
Current
Drift velocity
Electric field
Current density

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

In a steady state, the current flowing through any cross-section of a conductor remains constant regardless of the cross-sectional area. Therefore, current remains constant throughout the metallic conductor.
