0:01
the instantaneous value of the induced
0:03
EMF as a function of time is eal to e
0:08
sin Omega T where e is the P value of
0:14
EMF the instantaneous value of the EMF 1
0:18
qu of the period is what now we are to
0:22
find the instantaneous value of the EMF
0:27
given instantaneous value which is the
0:42
induced the induced EMF as a function of
0:45
time is this which is
0:49
instantaneous EMF where e not is the P
0:53
value e not is the P value which
0:57
means e is equal to e not in this
1:05
case therefore we will now say
1:10
that of the EMF the instantaneous value
1:22
remember that this formula is the same
1:31
s this Omega T is also the senance Theta
1:37
and therefore we can now write it as e
1:39
not sin Theta and Theta is our
1:45
period which implies that if you have e
1:48
is equal to e which is the F uh
1:53
EMF now we have a qu of the
1:58
period and th is a period which means
2:01
that one qu and a period is the same
2:09
360° therefore 1 qu of this 360° is
2:16
360 * 1 qu which is 1
2:20
4 and this is going to give us 360 / 4
2:31
4 and this is going to give us
2:35
360 / 4 which is equals
2:43
90° therefore this is our
2:47
Theta and therefore now we can now say
2:50
that the instantaneous EMF e is equal to
2:55
e s since we have Theta here and our
3:03
90° therefore we can now say sin 90
3:09
de and this is equal to remember we are
3:12
not changing e because e is equal to e
3:15
therefore in this case now s of
3:27
1 therefore in this case
3:30
if if 9 = 1 therefore we now say that
3:35
this isal e * 1 this is equals to
3:41
one therefore this is going to give us e
3:46
therefore our e which is the
3:49
instantaneous value of the EMF is equal
3:53
to the fake value of the EMF e isal to e
3:59
and this is our final
4:01
answer as you can see this is what we
