Here in a series series rl circuit the current i l t is i l at 10 t is equals to the v node divided by the r because i is equal to v divided by the r simply here i note v divided by r multiplies by the 1 minus e raised to the power minus t divided by the toe.
00:28
So this is here where the value of v note is equal to the 35 volt.
00:36
So the value of t, toe is equal to l divided by the r, the value of r is 0 .00, 1 to 5 and the value of r is 50.
00:46
So after simplifying this we get the value of toe as 2 .5, multiplies by the 10 x2 .5.
00:53
So this is the value of toe.
00:55
So from here we can write it as state il of 5.
00:58
T is equals to the 0 .7 multiplies by the 1 minus e raised to the 5 minus 40 ,000 t which is further multiplies by the a so here in the part 1 let's say let i .mximum is equals to 0 .7 ampere and the half of its half of its is 0 .7 divided by 2 is 0 .7 0 .45 we can write it as or we can write it as 0 .7 divided by 2 is equals to 0 .7 multiplied by the 1 minus e raised to the power minus 40 ,000 t so from here we can write it it is that 0 .5 is equals to 1 minus e raised to the power minus 40 ,000 t so from here we can write the test at 0 .5 is equal to 1 minus e raised to the power minus 40 ,000 t also from here we can write the test 0 .5 is equal to e to the power minus 40 ,000 t so taking the talking on the both sides we can write it as 40 ,000 t is equal to minus 0 .693 so the value of t comes out to be 17 .33 microseconds...
