- c)26%
- d)81%
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
In a centre tapped full wave rectifier, RL=1KΩ and for diode Rf=...
The ripple factor ϒ= [(IRMS/IAVG)2 – 1]1/2. IRMS =Im /√2=Vm/(Rf+RL)√2=200/1.01=198.
(Secondary line to line voltage is 800/2=400. Due to centre tap Vm=400/2=200)
IRMS=198/√2=140mA, IAVG=2*198/π=126mA. ϒ=[(140/126)2-1]1/2=0.48. So, ϒ=48%.
