Explanation:
Given In transistor the collector current changes by 0.99 mA with a 1mA change in the emitter current. What is the common base current has of the transistor?
- Given the collector current changes by 0.99 mA and change in emitter current is 1 mA.
- Therefore current gain = Δ Ic / Δ Ie
- Now Δ Ic = 0.99 mA
- Also ΔIe = 1 mA
- Therefore current gain = 0.99 x 10^-3 / 1 x 10^-3
Current gain = 0.99
