the number of electrons striking the screen of CRT is 7.5×10^15 in 10 sec. calculate the electric current
Asked by saishankar160 | 10 Feb, 2022, 09:57: PM
Expert Answer
Current = charge / time
Charge = no of electrons × e
where e = 1.602 × 10-19 C
Current = ( 7.5 × 1015 × 1.6 × 10-19 ) / 10 = 120 × 10-6 A = 120 μA
