Two lamps of 200W,220V and 100W,220V are series across 220V.Ratio of current.i) 1:2 ii) 1:1 iii) 2:1 iv)1:4
Whatever may be the resistances the current flows equally among all the elements in series.
so ratio of currents = 1:1
Since they are connected in series,,,,so the current across two bulbs will be equal...
Hence ratio is 1:1
If you connect it in parallel.....then also you will get a current ratio 2:1...not 1:2
Hence 1:2 is not any possible answer...
