Statement-1 : A transistor with common emitter mode has current gain `50`. When base current is `5 muA`, the emitter current is `0.255 mA`.
Statement-2 : `I_(e)=I_(b)+I_(c)`
and `beta=I_c//I_b`

Options

A. Statement-1 is true, Statement-2 is true, Statement-2 is a correct explanation of Statement-1.
B. Statement-1 is true, Statement-2 is true, Statement-2 is not a correct explanation of Statement-1.
C. Statement-1 is true, Statement-2 is false.
D. Statement-1 is false, Statement-2 is true.

Answer

A

Explanation

Here, both statement-1 and statement-2 are correct and statement-2 is correct explanation of statement-1. As `I_(e)=I_(b)+I_(c)=I_(b)+betaI_(b)`
`=I_(b)(beta+1)=5mu A(50+1)`
`=255 muA=0.255 mA`
