b. Voltage gain	f. $\frac{\Delta I_c{R}_L}{\Delta I_b{R}_i}$
c. Power gain	g. $(\frac{\Delta I_c}{\Delta I_b}{)}^2\frac{R_L}{R_i}$
d. Resistance gain	h. $\frac{R_L}{R_i}$

Match the above for C E transistor amplifier

• A. a - e, b - f, c - g, d - h
• B. a - f, b - g, c - h, d -e
• C. a - g, b - h, c - e, d - f
• D. a - h, b - e, c - f, d - g

Answer 1

Answer: (A)

a - e, b - f, c - g, d - h

Current gain, $\beta =\frac{\Delta I_c}{\Delta I_b}$.
Voltage gain $=$ current gain $\times$ resistance gain.
Power gain $=$ (current gain)${}^2$ $\times$ resistance gain.
Resistance gain $=\frac{R_L}{R}$
