Question

If base current is 50 a .Find the range of collector current

Answer 1

For an unbiased transistor, considering only the BE junction which is a pn junction diode, 0.7V is the potential barrier. In an npn transistor base is positive(p) and emitter is negative(n). So the potential barrier vbe=0.7V.

Answer 2

Explanation:

Ib=50 micro amp

B = 25

Ic = Current gain

Ic= Ib × β

== 50×25

==1250 ma

==1250/1000 =1.25 ma
