Question

17. Two resistances R1 = (100 ± 3) Ω, R2 = (150 ± 2) Ω, are connected in series. What is

their equivalent resistance​

Answer 1

Explanation:

in series,Rnet=R1+R2=100+150=250ohms.

for error,take partial differentiation both sides,d(Rnet)=d(R1)+d(R2)=3+2=5ohms.

therefore,net R=250+-5ohm
