Question

The total power content of a $AM$ wave is $1500W$. For $100\%$ modulation, the power transmitted by the carrier is

• A. $500W$
• B. $700W$
• C. $750W$
• D. $1000W$

Answer 1

The correct option is D $1000W$

$P_T=\frac{{V_c}^2}{2R}\left(\frac{2+m{a}^2}{2}\right)=P_c=\frac{{V_c}^2}{2R}$

$1500=P_c\left(\frac{3}{2}\right)$

$\Rightarrow P_c=1000W$

Hence,

option $\left(D\right)$ is correct answer.
