Answer:
If 80 micro amphere pass through the TV every second then the amount of current that pass through the tv in 2 minutes will be 9,600 Mah.
Explanation:
Amount of current passes through the beam=80Mah
Amount of current that passes through the t.v in 2 minutes=? 80×120
=9,600 Mah
Thanks, hope it helps you.

Answer:-
I = q/t
q = ne
for no. electron per sec
ne = I = 80 × 10^-6
n = 80 x 10^-6 ÷(1.6x10^-19)
= 50x10^13 (is the number of electrons that strike the screen per second)
in two minute
q = It
= 120x80x10^-6
= 9.6x10^-3 coulomb
