Question

The biasing circuit has a stability factor of 40. If due to temperature change, ico changes by 1a, then ic will change by

Answer 1

Given :

Stability factor(S) = 40

Change in current (ΔIco)= 1A

To find :

The change in Ic = ?

Solution :

• We know the formula S = Ic / ΔIco

• By substituting the values

     Ic = S × ΔIco

         = 40 × 1

     Ic = 40A

The change in Ic will be 40A
