1.

the situation shown, the currents through 39 and 223. in the situationresistances are in the20322522

Answer»

1,2 are in series so equivalent is 3,4,5 are in series so equivalent is 9,now 3 and 9 are in parallel so equivalent is 9/4 now 9/4 and 3 are in series so equivalent is 21/4

current through 3 is 'i'current through 2 will be 9i/12ie 4i/3A then the ratio of 3 to 2 current = 3/4
