Problem: What is the equivalent resistance between points a and b in the figure? (Figure 1)Please show work.

FREE Expert Solution

Let's label the resistors as:

Equivalent resistance for 2 resistors in parallel:

Req=R1R2R1+R2

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Resistors 1 and 2 are in parallel:

R12 = (30)(45)/(30 + 45) = 18Ω
