In this question, there is a load resistance r and this is connected to the ac source.
00:09
Ac source.
00:10
So the voltage expression is maximum voltage.
00:14
This is sine omega t.
00:15
So it is the function of sign.
00:17
So we can write the expression of current.
00:19
This is peak current.
00:21
This is sign angular frequency.
00:24
Time constant.
00:26
So time constant is given as 7 .50 milliseconds.
00:31
And the value of current is equal to 79 % of peak current.
00:38
So we can write current is 0 .79 times peak current.
00:43
And angular frequency we can write 2 pi.
00:46
This is the frequency of the ac source and time constant.
00:50
So we can write sign inverse...
