If the transistor in the figure is in saturation then,

Question

If the transistor in the figure is in saturation than,

(a) ic is always equal to β_dci_b.

(b) ic is always to - β_dci_b.

(c) ic is always to β_dci_dc.

(d) ic is less than β_dci_b.

Answer 1

 Correct Option (d) i_c is less than β_dci_b.

Explanation:

For transistor in common emitter mode the relation between collector current and collector emitter voltage is given by v_ce= v_cc-I_CR_C

cut off

 occurs when I_c= 0 

Saturation

 It occurs when there is no longer a change in collector current for a change in base current

 Active Mode

 In this mode the following relation is valid i_c =β I_β

Thus in saturation the collector current does not increase with base current
