PARALLEL

Simplified circuits are very useful when

solving series-parallel circuit problems.

5 OHMS

Draw and use simplified circuits when solving

the problems in this program.

Figure B is the simplified drawing of the

circuit in figure A. To solve for the total

resistance of the circuit below, first, solve

for the combined resistance of the series

network R1, R2, and R3. This combined value is

represented in the simplified circuit as Ra.

Second, solve for the combined value of R4 and

R5. This combined value is represented in the

simplified circuit as Rb.
