This is a Multiple Choice Questions as classified in NCERT Exemplar

Answer- a, b, d

Explanation- The space-charge regions on both the sides of p-n junction which has immobile ions and entirely lacking of any charge carriers will form a region called depletion region of a diode.

The number of ionized acceptors on the p -side equals the number of ionized donors on the n-side.

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________.

alok kumar singh

Voltage gain = $\frac{Δ l_{C}}{Δ l_{B}} \times \frac{R_{C}}{R_{B}}$

$\frac{5 \times 1 0^{- 3}}{100 \times 1 0^{- 6}} \times \frac{2}{0.5}$
