The potential difference applied to an X-ray tube is 5 kV and the current through it is 3.2 mA. Then the number of electrons striking the target per second is
Text Solution
Verified by ExpertsThe correct answer is:
A
Given, potential difference,
and discharge current,
As, We know that current,
where,
number of electron,
charge on electron and
time

Putting
and 

Hence,
electrons are striking the target per second.
