Physics - Semiconductors Question with Solution | TestHub

Given the DC output voltage $V_{dc}=20\text{V}$ and the RMS value of the AC component $V_{ac}=2\text{V}$.

The ripple factor $\gamma$ is defined as the ratio of the RMS value of the AC component to the DC component of the output voltage:

$\gamma =\frac{V_{ac}}{V_{dc}}$

Substituting the given values:

$\gamma =\frac{2}{20}=0.1$

Expressing the ripple factor in percentage:

$\gamma =0.1\times 100\%=10\%$

Answer: $10\%$
