If the potential difference applied across a Coolidge tube is increased , then

A

The value of `lambda_m`decreases.

B

The value of `lambda_alpha` increases

C

The value of both `lambda_alpha` and `lambda_alpha` increases

D

The value of `(lambda_alpha -lambda_m)` increases

Text Solution

Verified by Experts

The correct Answer is:
A, D
Since the value of applied potential difference is increased, the value of `lambda_m` will decrease. `(lambda_m prop 1/V)` However the value of `lambda_alpha` is independent of the applied potential difference across the tube. Since the value of `lambda_m` decreases, the difference `(lambda_alpha -lambda_m)` will also increase.
