Question

current gain in a transistor is 0.95 . in a CE arrangement ,if o.4 mA is the charge in base current ,charge in collector current is (a) 7.6 mA (b)8.4mA (c)1.8mA (d)none with a solution​

Answer 1

Answer:

Time taken by a current to deliver a charge.

==================================☆

As we know,

That current is the charge flowing per unit time from a conductor,

current (I) = charge flowing in conductor (q) /time taken (t)

here

q = 15 C

I = 5 mA

= 5 × 10^-3 A

So,

By I = q/t

t = q/I

t= 15/ 5× 10^-3

t = 3 × 10^3

t = 3000 sec

3000 sec ,time it will take to pass a current 5mA , of to deliver a charge of 15 columb.
