NEET Questions Solved


In a typical Wheatstone network, the resistances in cyclic order are A = 10 Ω, B = 5 Ω, C = 4 Ω and D = 4 Ω for the bridge to be balanced 

(1) 10 Ω should be connected in parallel with A

(2) 10 Ω should be connected in series with A

(3) 5 Ω should be connected in series with B

(4) 5 Ω should be connected in parallel with B

(1) For a balance Wheatstone bridge.

AB=DC10544 (Unbalanced)

A'B=DCA'5=44A'=5Ω

A'(5Ω) is obtained by connecting a 10Ω resistance in parallel with A.
