Expert Answer
Number of electrons striking per second is required to calculate current.
Proper question is given below :-
The number of electrons striking the screen of CRT is 7.5×1015 in10s calculate the electric current
---------------------------------------------
current = charge / time = ( Number of elecrons × charge on electron)/time
Hence current = (7.5×1015 ×1.602×10-19 ) / 10 ≈ 12×10-5 A = 120 μA
