PMT - 2000

The effective resistance between points A and B is 

(1) 10 Ω

(2) 20 Ω

(3) 40 Ω

(4) None of the above three values

(1) This is a balanced Wheatstone bridge. Therefore no current will flow from the diagonal resistance 10 Ω

∴ Equivalent resistance =(10+10)×(10+10)(10+10)+(10+10) = 10 Ω
