R1 = 1 ohm
R2 = 100 ohm
==> 1 / Équivalent R = 1/R1 + 1/R2
==> 1/R = 1 + 1/100
==> 1/R = 100 + 1 /100
==> 1/R = 101/100
==> R = 100/101
==> R = 0.99 ohm

Answer:
Judge the equivalent resistance when the following are connected in parallel 1. 1ohm and 10^6 2. 1 ohm , 10^3ohm, 10^6 ohm...
Resistance when connected in parallel
1/Rp = 1/R1 + 1/R2
Case 1
R1 = 1 Ω
R2 = 10^6 Ω = 1000000 Ω
1/Rp = 1/1 + 1/1000000
=> 1/Rp = (1000000 + 1)/1000000
=> 1/Rp = 1000001/1000000
=> Rp = 1000000/1000001
=> Rp = 0.999999 Ω
=> Rp ≈ 1 Ω
Case 2 - Statement is not cler.
