Relation between Current and Drift Velocity: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Relation between Current and Drift Velocity. Understanding the underlying formula is key to arriving at the correct answer below:

The relation between current (I) and drift velocity \(v_d\) is \(I = nAe v_d\), where (n) is carrier density, (A) is cross-sectional area, and (e) is electron charge. This equation shows that current is directly proportional to drift velocity. Therefore, both Assertion (A) and Reason (R) are false.
