00:00:00,000 --> 00:00:04,000
This is a series-parallel combination.

1
00:00:04,000 --> 00:00:09,000
First you have to solve the series branch of two resistors O10kΩ.

2
00:00:09,000 --> 00:00:13,000
Then the parallel branches of 2 and 20kΩ.

3
00:00:13,000 --> 00:00:18,000
Remember that it is necessary to use the calculator and the equivalent resistor is the inverse.

4
00:00:18,000 --> 00:00:21,000
Again use the inverse key in the calculator.

5
00:00:21,000 --> 00:00:25,000
Finally the resulting circuit has three resistors in series.

6
00:00:25,000 --> 00:00:29,000
Add the three of them and you obtain the equivalent circuit.
