Suppose you are given several resistors whose resistances are within the range 15 to 40 Ω. You connect them all in series and let your three partners measure the equivalent resistance. Three different measurements have been obtained: 8, 34 and 92 Ω. Which of these three you would assume to be correct?

Question

Suppose you are given several resistors whose resistances are within the range 15 to 40 Ω. You
connect them all in series and let your three partners measure the equivalent resistance. Three
different measurements have been obtained: 8, 34 and 92 Ω. Which of these three you would
assume to be correct? 

Expert Solution
Step 1

Range of resistance 

R =  15 to 40 Ω

Three different measurements of series combination of three resistance in this range 

 First measurement gives 

R1 = 8 Ω

 Second measurement gives 

R2 = 34 Ω

Third measurement gives 

R3 = 92 Ω
