Hello students, so in this question the first part that is the rlc circuit right.
00:09
So, we have here r, l and c.
00:24
So, we have a voltage difference here which is plus and minus right this is r, this is l and this is c.
00:39
So, according to this we voltage of this is vr, vn and vc right.
00:47
So, in resistance voltage and current are in same phase right, voltage and current are in same phase whereas in inductor the voltage leads current in this case and in this case voltage lags current right.
01:11
Now, the second part that is the voltage relation.
01:16
So, vn equals j right j.
01:24
So, voltage is basically current multiplied by the resistance xl, vc equals minus j ixc right and vr is as it is vr.
01:42
So, the total voltage becomes total voltage becomes vr plus j vl minus vc.
01:52
So, this becomes root over of vr square plus vl minus vc square.
01:58
So, this gives us when we calculate this root over of 3 .33 square plus 3 .14 minus 0 .3 square.
02:13
So, this turns out to be equal to 6 .84.
02:20
So, it 4 .41 volts right.
02:28
Now, the second part that was the first part vr equals 2 .8 volt, vl equals 2 .6 volt and vc equals 6 .15 volt then v turns out to be 4 .52 volt.
02:48
The third one vr equals 3 .4 volt, vl equals 5 .54, vc equals 1 .01 volt.
03:01
So, this turns out to be 5 .63 volt right.
03:07
So, from calculated value and measured value there is slight differences.
03:14
So, this is not 6 .84, this is not 6 .58 and this is not 4 .5 right.
03:25
So, now we will calculate the impedance relation right...
