We'd like to solve this circuit problem.
00:04
Let's first find our equivalent resistance.
00:07
We see that we have some resistors in parallel, such as our 2 ohm and our 40 ohm.
00:14
Yeah, we have some that are in.
00:22
We have 2 and 240.
00:29
So let's go ahead and solve this problem.
00:33
We want to solve for the equivalent resistance.
00:40
We can write 1 over resistance 1 equal to 1 over 2 ohms plus 1 over 240.
00:46
And so taking the inverse, resistance 1 is 1 .98 ohms.
00:51
Let's combine this with our 40 ohm resistor.
00:54
So 1 over r2 is 1 over 1 .98 plus 1 over 40.
00:59
Taking the inverse, r2 is 1 .89 ohms.
01:05
Now combine this with our 20 ohm resistor...
