The combined resistance R02 in this series-parallel connection can be determined in the following order:

a. Determine combined resistance R01, which is a combination of resistances R2 and R3 connected in parallel.

b. Then, determine resistance R02, which is a combination of resistance R1 and combined resistance R01 connected in series.

Total current I flowing in the circuit can be determined from Ohm's law as follows:

The voltage applied to R2 and R3 can be found by the following formula:
