For a transistor, `beta` = 50. To change the collector current by 350 `mu`A, the base current should be changed by
A. `(50/350)muA`
B. `(350-50)muA`
C. `(350+50)muA`
D. `(350/50)muA`
A. `(50/350)muA`
B. `(350-50)muA`
C. `(350+50)muA`
D. `(350/50)muA`
Correct Answer – D
`beta=50 = (DeltaI_C)/(DeltaI_B)`
`therefore DeltaI_B= (DeltaI_C)/beta=(350/50)muA`
