Given that,

\mathrm{\begin{aligned} & R_L=24 \Omega \text { and } R_I=3 \Omega \\ & \therefore \quad \text { Resistance gain }=\frac{R_L}{R_1}=\frac{24}{3}=8 \\ & \therefore \quad \text { Voltage gain }=\text { current gain } \times \text { resistance gain } \\ & \quad=0.6 \times 8=4.8 \end{aligned}}
