Answer:
20
Explanation:
Inorder to get a min. resistance, we should connect the resistance in parallel series combination.
1/r1 + 1/r2 + 1/r3 = 1/Rp
1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 = 20/10 = 2 Ω
Therefore 20 resistors are required
