Answer 2

Answer:

The effective circuit is shown in the figure.

The resistance of arm EHG=10Ω+10Ω=20ΩEHG=10Ω+10Ω=20Ω

will be parallel to resistance of arm

FG=10Ω+10Ω=20ΩFG=10Ω+10Ω=20Ω

Their effective resistance =20Ω×20Ω20Ω+20Ω=10Ω=20Ω×20Ω20Ω+20Ω=10Ω

Therefore, the equivalent resistance between AA and

D=5Ω+10Ω+5Ω=20Ω
