Hi students in this question, a c .d's lr circuit is been given with the value of inductance l to be equal to 10 into 10 raise to minus 3 henry.
00:11
On the other hand, the value of resistance r is taken to be 10 o.
00:15
Now the emf of the battery is taken as e, which is equal to 6 volts.
00:20
And in the first part of the question, we need to find out that time t for which the current i will be equal to 95 % of the maximum current, which is taken.
00:30
As i0.
00:31
Now the equation which is used for representing the maximum current is taken as i0 to be equal to the emf of the battery e divided by resistance r.
00:40
And here by substituting the value of e and r in this equation, we get i0 to be equal to 6 divided by 10 which is equal to 0 .6 ambia.
00:50
Now in order to find the value of time t, we have to use the equation of current, that is current i will be equal to maximum current i 0 into 1 minus exponential value of minus r into time t divided by inductance value l...
