CURRENT-3

Current in R_(3)

In the given circuit diagram, the currents, I_1=-0.3A,I_4=0.8A and I_5=0.4A , are flowing as shown. The currents I_2,I_3 and I_6 respectively, are :

3g of metal ions were discharged at cathode using a current of 3 amperes for 2 hours from aqueous cupric sulphate solution. Calculate the current efficiency. At wt . of Cu is 63.5 .

In the circuit shown in figure For what ratio (R_(2))/(R_(4)) , current through R_(3) will be zero

Two coils 'P' and 'Q' are separated by some distance. When a current of 3A flows through coil 'P' a magnetic flux of 10^(-3) Wb passess through 'Q'. No current is passed through 'P' and a current of 2A passes through 'Q', the flux through of 'P' is :
