Problem 19.40 7 of 16 Constants Part A Assume that R1-41 Ω , R: 78 Ω . R: 11 Ω , R1-14 Ω R5 10 Ω , and R6-24 Ω Find the equivalent resistance of the combination shown in (Figure 1). Express your answer in ohms to two significant figures. Figure Submit Request Answer 1 o14> 25 Ω 12Ω 5.0 Ω Part B Find the equivalent resistance of the combination shown in (Figure 2). Express your answer in ohms to two significant figures. Submit

Answer 1

a) resistances are in parallel

1/R(equi) = 1/R1 + 1/R2 + 1/R3 + 1/R4

1/R(equi) = 1/25 + 1/12 + 1/5 + 1/41

R(equi) = 2.875 ohm

so the equivalent resistance is 2.875 ohm
