Lesson 4: Reducing Simple ParallelSeries Combination Circuits
Resistors R_{2} and R_{3} are connected in series and make up one branch of a parallel circuit. Resistor R_{1} is the second branch. The total resistance of this circuit is given by:
This circuit is reduced to equivalent values by first summing R_{2} and R_{3} to get the value of equivalent resistor R_{2, 3}, and then combining R_{1} with R_{2, 3} to get the total equivalent resistance, R_{1,2, 3}. 
Example Systematically reduce this circuit to its equivalent resistance. 

Step 1: Combine resistors R_{2} and
R_{ 3} to form the equivalent resistance, R_{2, 3}.


Step 2: Combine R_{1} with
equivalent resistance R_{2, 3} to complete the reduction procedure.
