A wire whose cross-sectional area is incereasing linearly from its one end to the other, is connected across a battery of V volts. Which of the following quantities remain constant in the wire ?
Text Solution
AI Generated Solution
To solve the problem, we need to analyze the quantities associated with a wire whose cross-sectional area is increasing linearly from one end to the other when connected to a battery of V volts. We will evaluate which of the following quantities remain constant in the wire: drift speed, current density, electric current, and electric field.
### Step-by-Step Solution:
1. **Understanding the Wire Configuration**:
- We have a wire with a cross-sectional area that increases linearly from one end (let's call it end A) to the other end (end B).
- The wire is connected to a battery providing a voltage \( V \).
