Explanation:
Detailed explanation-1: -Expert-Verified Answer Minimum resistance is obtained by connecting all three resistances in parallel => 1/R =1/4+1/6+1/8 =>1/R = 6/24+4/24+3/24 => 1/R = 13/24 => R =24/13 ohm .
Detailed explanation-2: -Explanation: 3+6.02+12 = 21.02 Ohms.
Detailed explanation-3: -According to the question the equivalent resistance of 3 ohm and 6 ohm resistance which kept in parallel is 2 ohm.
