see dis one..
a half wave rectifier is being used to rectify an alternating voltage of freqncy 50Hz d no of pulses of rectified currt obtained in one sec is
50
25
100
200

1answers of semii2 and semiii3 r contradicting ..............y so?
24sorry if i am asking stupid question....
but explain this
""note only d time in these probs""
24why 1 sec doesnt matter??
f=50 Hz =>Time period=1/50=0.02 seconds..........
i hope i am not going wrong way.....[2][2][2]
1@eureka
note only d time in these probs.. here theres no prob in gettin confused as its one sec...
1@mrunal.. yup.. d only thing is dat d amount of ac rectified in two casesi.e half d cycle in hwr n d full wave in fwr.... n not d frequency...
1mera q bata ........
n eureka dnt wrry .......mera hi bouncer ja ra hai thoda thoda..........
24@ ram.......no worries....[1][1]
ok i understood the concept........but how to do questions related to this.......this question which u and mrunal are discussing ,I cant get that.......[2][2]
1fullll wave n half wave dohno ke liye freqncy same as b4 rahegi ??
1sorry eureka.. see post no /#8.. it was fr u .. by mistake i put @celestine..
1k so
fullll wave n half wave dohno ke liye freqncy same as b4 rahegi ??
1kaise 25 aayega???
no again.. theres no frequency change in any rectifier,,
1k so in full wave freqncy doubles n in half wave it remaisn d same
rite ??
1nw it shud b 25 na.........
.sorry that 100 was by mistake
really solvd few q's of this chap n 100 was 4 sum othr sum :)
1@mrunal.. naa.. theres no change in frequency..
see d dotted lines in d diagram...
1@mrunal.. so as u thought d ans 100 its only wen fullwave rectifier is used...
1@eureka
a half wave rectifier is used to convert half of d in put ac voltage or current to dc voltage or current using a diode...
i.e only d positive cycle of ac is converted to dc..by principle of diode.. i.e current flow is only wen forward biased
wait for full wave rectifier
24can some one explain me whats the function of full wave and half wave recitifier....and how to solve probelms related to this topic........
i read NCERT but understood nothing.....[2][2]
1coz in one sec after rectifyin d negative cycle has no current...
1i hope no formula involved in dis.. only practical knowledge,,,
