Answer- b, c

Explanation- I_C= 10mA

I_c= 95/100 I_e

I_e= $\frac{10 * 100}{95}$ = 10.53mA

I_b=I_e-I_C= 10.53-10= .53mA

A transistor is used in an amplifier circuit in common emitter mode. If the best current changes by 100 $μ A,$ it brings a change of 10 mA is collector current. If the load resistance is 2 $k Ω$ and input resistance is 1 $k Ω,$ the value of power gain is x × 10⁴. The value of x is_____________.

alok kumar singh

Power gain = ${(\frac{Δ i_{c}}{Δ i_{b}})}^{2} \times \frac{R_{0}}{R_{i}}$

= ${(\frac{10 \times 1 0^{- 3}}{100 \times 1 0^{- 6}})}^{2} \times \frac{2}{1}$

= 2 × 104 = x × 104

= 2

The typical transfer characteristics of a transistor in CE configuration is shown in figure. A load resistor of $2 k Ω$ is connected in the collector branch of the circuit used. The input resistance of the transistor is $0.50 k Ω .$ The voltage gain of the transistor is________.
