Question

In a transistor amplifier, $\beta = 62$, $R_L = 5000\,\Omega$ and input resistance of the transistor is $500\, \Omega$. What is power amplification ?

• A. $6200$
• B. $45850$
• C. $38440$
• D. $15320$

Answer 1

Answer: (C)

$38440$

Answer 2

$Given : \beta = 62, R_{L} = 5000 \,\Omega, R_{i} = 500\,\Omega$ Power amplification, $A_{P} = \beta^{2} \cdot\frac{R_{L}}{R_{i}} = \left(62\right)^{2} \times\frac{5000}{500} = 38440$
