The number of electrons strike the screen each minute when thee current in the electron beam of a typical video display terminal is 200 µa is 7.5×10¹⁶.
<h3>How to calculate electric charge?</h3>Electric charge is equal to the product of electricity current flowing and the total time. It can be given as,
Here, I is current and t is time.
The current in the electron beam of a typical video display terminal is 200 µa for one minute. Thus, the total charge is,
The number of electron flow is the ratio of total charge to the charge of one electron. The charge on one electron is 1.6×10⁻¹⁹ C. Thus, the number of electron is,
Thus, the number of electrons strike the screen each minute when the current in the electron beam of a typical video display terminal is 200 µa is 7.5×10¹⁶.
