In the diagram resistance between any two junction is R.Equivalent resistance across terminals A and B is In thccirvuit in figure reading ofvolttneter is when only Sl is closed. rvading of volttncter is V2 when only S, is closed. The reading otÅoItmeter is when both Sl and S2 are closed then end ofa Nichrome wire of length and cross-sectional area A is a-.tatched to an end of another Nichrome wire of length L and cross-sectional area 2A. Ifthe free end of the longer wire is at an electric potential of SO volts, and the free end of the shorter wire is at an electric potential of | .0 volt, the potential at the junction of the two wires is equal to (C) 4.5 v (A) 2.4 V (B) 3.2 V (D) 5.6 V Q.--,s In the diagram resistance between anytwojunctions is R. Equivalent resistance across terminals Aand B is IIR (A) 7 18R 11 11 IIR (D) 18 Q.29 Power generated across a uniform wire connected across a supply is H. Ifthe wire is cut into n eqt pans and all the parts are connected in parallel across the same supply, the total power generated in v.ire is (B) n2H
