Judge the equivalent resistance when the following are connected in parallel `to" a."1Omegaand10^(6)Omega."b".1Omegaand10^(3)Omegaand10^(6)Omega`.

Explanation

i] `1/R=1/1+1/10^(6)+1=1000001/1000000`
`R=1000000/1000001Omega`
`1/R=1/1+1/10^(3)+1/10^(6)=10^(6)+10^(3)+1/10^(6)`
= `1000001/1000000`
ii] `R=1000000/1000001=0.9Omega` (approx.)
