0:02
frequency of the EMF SCE in the AC
0:05
circuit Illustrated above is 500
0:09
5z what is the reactance of the
0:13
inductor now you need to
0:16
remember that the formula for the
0:20
the inductance XL is equal to 2
0:31
L and as you can see from this diagram
0:37
we have L which is Henry which is in
0:40
Henry sorry the inductance L is equal to
0:51
and if the frequency of the MF EMF
0:55
Source in the AC circuit Illustrated
1:01
500 over 5 HZ which means
1:25
now when we use the formula XL = to
1:30
2 5 f l we're going to end up with 2 * 5
1:39
times our F here is 500 over 5z
1:48
5 times our L here is
1:56
0.9 and this is going to give us
2:01
from here five will cancel 5 therefore
2:04
we're going to have 2 * 500 this is
2:07
going to give us 9 uh
2:16
09 and therefore when we do it 0.9 *
2:20
1,00 is going to give us
2:27
XL therefore our XL is going to be
2:31
900 and since we have to find the
2:35
reactance of the inductor which is going
2:38
to be in amps therefore we say
2:43
900 amps which is the final answer
