If the current gain in common-base configuration ( ) of a transistor increases from 0.95 to 0.96, the percentage change in current gain in common-emitter configuration ( ) is approximately

Step-by-step solution

The relation between common-emitter current gain and common-base current gain is given by = 1 - . For the initial state, ₁ = 0.95 . ₁ = 0.95 1 - 0.95 = 0.95 0.05 = 19 For the final state, ₂ = 0.96 . ₂ = 0.96 1 - 0.96 = 0.96 0.04 = 24 The change in current gain is = ₂ - ₁ = 24 - 19 = 5 . The percentage change in is ₁ 100 = 5 19 100 26.31 % . Thus, the percentage change is approximately 26 % . Answer: 26 %
