Two identical light bulbs are placed any-where in any circuit . Let the current through #1 be i1 and the power consumed by #1 be P1, and the corresponding quantities i2 and P2 for bulb #2 . If the ratio P1/P2 = 2 , the ratio i1/i2 will be given by ?

(i) i1/i2 = 1/6

(ii) i1/i2 = 2

(iii) Not enough information

(iv) i1/i2 = square root 2 .
