In the study of transistor as an amplifier, the ratio of collector current to emitter current is 0.98 then the ratio of collector current to base current will be

Step-by-step solution

The ratio of collector current to emitter current at constant collector base voltage is the current the amplification factor and given by α = l C l E = 0.98 (Given) The ratio of collector current to the base current at constant collector-emitter voltage is given by β = l C l B These are related as β = α 1 - α ⇒ β = 0.98 1 - 0.98 = 0.98 0.02 = 49
