Problem: Suppose that R = 70 Ω.What is the equivalent resistance between the points a and b in Figure 1? Express your answer with the appropriate units.Rab = ____

FREE Expert Solution

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Equivalent resistor for resistors in parallel:

1Req=1R1+1R2+...+1Rn

60Ω and 40Ω are in parallel.

1/Req1 = 1/60 + 1/40 = 1/24

Req = 24Ω

60Ω, 60Ω, and 45Ω resistors are in parallel:

1/Req2 = 1/60 + 1/60 + 1/45 = 1/18
