In a CE transistor amplifier, the audio signal voltage across the collector resistance of $2 K Ω$ is 2V. if the base resistance is $1 K Ω$ and the current amplification of the transistor is 100 the input signal voltage is

Options:

Answer:

Solution:

We know that Voltage amplification is given by :

$\frac{V_{0}}{V_{i n}} = β \frac{R_{L}}{R_{i}}; \frac{2}{V_{m}} = 100 \frac{(2 \times 10^{3})}{1 \times 10^{3}}$
