Physics - Semiconductors Question with Solution | TestHub

The ripple factor of a rectifier is a measure of its effectiveness in converting AC to DC.

It is defined as the ratio of the root mean square (rms) value of the AC component to the DC component (average value) present in the output of the rectifier.

Mathematically, it is given by $\gamma =\frac{I_{ac(rms)}}{I_{dc}}$ or $\gamma =\frac{V_{ac(rms)}}{V_{dc}}$.

Answer: rms value of AC component to value of DC component, in the rectifier output.
