Okay, so we have a combination circuit here with series and parallel resistors.
00:09
And so, of course, we'll be using omslaw, v equals ir.
00:19
And so what we can do, first of all, is simplify this circuit a little bit.
00:27
So we have our 5 -volt battery here and our 1 -oom resistor.
00:37
And then the rest of these, two, one, and this other two ome resistor can be added together to simplify this so that it looks like just two resistors in parallel.
00:55
So you would just add these together, two plus one plus two oms.
01:00
That's five oms.
01:05
So this is the same as this.
01:08
And now we have two resistors in parallel.
01:12
And we can find the equivalent resistance of the circuit.
01:15
So 1 over our equivalent equals 1 over this first resistor 1 ome plus 1 over 5 oms.
01:31
And solving for our equivalent, that's 1 over 1 oom plus 1 over 5 oms...
