Equivalent resistance for resistors in series:
Equivalent resistance for resistors in parallel:
Label the resistors as follows:
Resistors 5 and 7 are in series.
R57 = 10 + 2 = 12Ω
R57 is in parallel with R6
R567 = (12)(6)/(12 + 6) = 4Ω
R567 is in series with R8
R5678 = 4 + 8 = 12Ω
Consider the circuit shown in (Figure 1).
