(a) The equivalent resistance of two resistances `1 Omega` and `10^(6)Omega` connected in parallel will be less than `1 Omega`. This is because when a number of resistances are connected in parallel, then their equivalent resistance is less than the smallest individual resistance (which is `1 Omega` in this case).
(b) The equivalent resistance of three resistances `1 Omega, 10^(3)Omega` and `10^(6)Omega` connected in parallel will be less than `1 Omega`.
