Physics - Semiconductors Question with Solution | TestHub

$\mathrm{\alpha }$and$\mathrm{\beta }$both are amplification factors

$I_{\mathrm{E}}=I_{\mathrm{C}}+I_{\mathrm{B}}$

$\frac{I_{\mathrm{E}}}{I_{\mathrm{C}}}=1+\frac{I_{\mathrm{B}}}{I_{\mathrm{C}}}$

$\frac{1}{\mathrm{\alpha }}=1+\frac{1}{\mathrm{\beta }}$

$\mathrm{\alpha }=\frac{\mathrm{\beta }}{1+\mathrm{\beta }}$
