The potential different across the Coolidge tube is `20 kV and 10 m A` current flows through the voltage supply. Only `0.5%` of the energy carried by the electrons striking the largest is converted into X-ray. The power carried by the X-ray beam is `p`. Then

A

`0.1`

B

`1W`

C

`2W`

D

`10W`

Text Solution

Verified by Experts

The correct Answer is:
B
power drawn by coolidge tube =`20xx10^(3)xx10xx10^(-3)=200W`
Power of x-rays =`(0.5)/(100)xx200=1W`
