The ripple factor in a half wave rectifier is
- ✓$1.21$
- B$0.48$
- C$0.6$
- DNone of these
✓
Answer
Correct option: A.
$1.21$
a
(a)Ripple factor $r = \sqrt {{{\left( {\frac{{{I_{rms}}}}{{{I_{dc}}}}} \right)}^2} - 1} = \sqrt {\frac{{{{\left( {{I_0}/2} \right)}^2}}}{{{{\left( {{I_0}/\pi } \right)}^2}}} - 1} $$=1.21.$
(a)Ripple factor $r = \sqrt {{{\left( {\frac{{{I_{rms}}}}{{{I_{dc}}}}} \right)}^2} - 1} = \sqrt {\frac{{{{\left( {{I_0}/2} \right)}^2}}}{{{{\left( {{I_0}/\pi } \right)}^2}}} - 1} $$=1.21.$
