Hello, here we have to solve the given problem and first we have to find a total distance of this right.
00:05
Let's do this.
00:07
So let's start by looking at r1 and r2, r3, r4.
00:15
So r1 is in series, so in parallel with r2, r3, r4.
00:28
So therefore 1 over r total equals to 1 over 1 plus 1 over r2 3 4 then our total equals to r1 times r2 3 4 over the sum of r1 and r2 3 4 now we have to find this unknown r2 3 4 let's do this so r2 is in series we is r3 4 therefore r2 3 4 equals to r2 plus r3 or 4 and lastly we need to find this r3 4 r3 4 this guy the reciprocal of r3 4 equals to 1 over r3 plus 1 over r4 because r3 and r4 are in then r3 4 equals to r3 times r4 over the sum.
01:43
Let's calculate it.
01:48
Let's write it in a different color.
01:54
That equals to 8 times 4 oms divided by some of the atoms and 4 times 4 times.
02:08
Let's complete this calculation.
02:26
That equals to 2 .67 lumps.
02:32
Let me double check my calculation.
02:37
Yeah, that's correct...
