In a transistor, the collector current varies by 0.49 m A and emitter current varies by 0.50 A . Current gain β measured is

Step-by-step solution

Given, ΔI C = 0 .49 m A = 0 .49 × 10 - 3 A ΔI E = 0 .50 m A = 0 .50 × 10 3 A α = ΔI C ΔI E β = α 1 - α = 0 .49 0 .50 1 - 0 .49 0 .50 = 49 50 1 - 49 50 = 49 × 50 50 50 - 49 β = 49
