In a `n-p-n` transistor `10^(10)` electrons enter the emitter in `10^(-6)s`. `2%` of the elecrons are lost in the base. The current transfer ratio and the current amplification factor will beA. `0.98,49`B. `98,0.49`C. `0.49,98`D. `49,0.49`

Answer» Correct Answer - A
`alpha=(I_(C ))/(I_(B))=(0.98)`
`beta=(I_(C ))/(I_(B))=(0.98)/(0.02)=49`
