The number of electrons striking the screen of cathode ray tube is `7.5times10^(15)` in `10` seconds calculate the electric current.

The charge of an electron is 1.6 × 10^(19) C . How many electrons strike the screen of a cathode ray tube each second when the beam current is 16 mA

On increasing the number of electrons striking the anode of an X - ray tube , which one of the following parameters of the resulting X - rays would increase ?

In a discharge tube, the number of protons drifting across a cross-section is 1.5xx10^(18) per second, while the number of electrons drifting in opposite direction across that cross-section is 3.0xx10^(18) per second. Find the total current crossing the given cross- section.

In a hydrogen discharge tube, the number of protons drifitin across a cross section per second is 1.0xx10^(18) , while the number of electrons drifting in the opposite direction across the same cross section is 2.7xx 10^(18) per second. Find the curernt flowing in the tube.

When the number of electron striking the anode of an X - ray tube is increase , the ……. Of the emited X - ray increases , while when the speeds of the electrons the anode are increased , the cut - off wavelength of the emitted X - ray ……….

The number of electrons delivered at the cathode during electrolysis ny a current of 2 ampere in 120 seconds is (charge on electron =1.6xx10^(-19)C) :-
