Concept:

The ripple factor indicates the amount of AC content present in the rectifier's DC output. A lower ripple factor means smoother DC.

Ripple Factor Values:

Half-Wave Rectifier: \( r = 1.21 \)

Full-Wave Rectifier (including Bridge): \( r = 0.482 \)

Calculation:

\( \frac{1.21}{0.482} \approx 2.51 \)

This proves that the ripple factor of a half-wave rectifier is more than twice that of a full-wave rectifier.

Conclusion:

Hence, the correct statement is:

Option 3: A half-wave rectifier has more than twice the ripple factor of a full-wave rectifier.
