The current gain of a transistor in common – emitter mode is 49. The change in collector current and emitter current corresponding to the change in base current by 5.0 μA will be: |
245 μA, 250 μA 240 μA, 235 μA 260 μA, 255 μA none of these |
245 μA, 250 μA |
Here, $β = 49, ΔI_B = 5.0μA$ $∴ ΔI_C = βΔI_B = 49×5.0μA = 245μA$ $ΔI_E = ΔI_B + ΔI_C = 5.0μA+ 245μA = 250μA$ |
