Hello students, here we have to calculate the total resistance of this circuit.
00:04
So here r1 is 250 ohm and r2 is 200 ohm and r3 is 350 ohm.
00:16
R4 is 90 ohm and r5 is 75 ohm.
00:23
So first consider the series circuit that is r2, r3 and r4.
00:29
So we will get r is equal to r2 plus r3 plus r4.
00:37
So we will get r is equal to 200 plus 350 plus 90 that is equal to 640 ohm.
00:53
So we will get r is equal to 640 ohm.
01:02
Next consider the series that is r1 and r5.
01:06
R1 and r5 they are in series.
01:15
So we will get.
01:22
Next consider r1 and r5 they are parallel so we will get 1 divided by rp that is equal to 1 divided by r1 plus 1 divided by r5.
01:36
So we will get 1 by rp equal to 1 divided by 75 plus 1 divided by 250.
01:46
So we will get 1 by rp equal to 13 divided by 750...
