Assuming that the transistor is in active region and has a β (beta) value of 100, the collector current can be calculated as:
IC = βIB = 100 x 0.1mA = 10mA
Now, let's consider the effect of changing the base current by 10%:
IB' = 1.1IB = 1.1 x 0.1mA = 0.11mA
Assuming that the transistor remains in active region, the collector current can be approximated as:
IC' = βIB' ≈ βIB = 100 x 0.11mA = 11mA
Thus, the change in collector current is:
ΔIC = IC' - IC = 11mA - 10mA = 1mA
Therefore, the change in collector current is approximately 1mA when the base current is increased by 10%. It's important to note that this calculation is based on several assumptions and approximations, and the actual change in collector current may vary depending on the specific characteristics of the transistor and the operating conditions.
