Question

an electron gun in a TV set shoots a beam of electron the beam current is 4.8 microA how many electron strike the TV per second​

Answer 1

Given :  an electron gun in a TV set shoots a beam of electron the beam current is 4.8 microA

To find : how many electron strike the TV per second​

Solution:

Beam Current  I  = 4.8 μ A  = 4.8 * 10⁻⁶ A

Time = 1 Sec

Q = Charge

Q = It

=> Q = 4.8 * 10⁻⁶ * 1

=> Q = 4.8 * 10⁻⁶   C

Also Q  = ne

e =  1.6×10⁻¹⁹

n = number of electron Striking

=> 4.8 * 10⁻⁶ = n * 1.6×10⁻¹⁹

=> n = 3 * 10¹³

3 * 10¹³   or  30 Tera  Electrons Strike per Seond
