" If two electric bulbs have "40W" and "60W" rating at "220V" ,then the ratio of their resistances will be "

If two electric bulbs have 40 W and 60 W rating at 220 V , then the ratio of their resistances will be

If two electric bulbs have 40 W and 60 W rating at V 220 , then the ratio of their resistances will be

When two electric bulbs of 40W and 60W are connected in parallel, then the:

Two bulbs of (40W 200V) and (100W 200V). Then correct relation for their resistances:

There are two electric bulb : (i) marked 60 W, 220 V and (ii) marked 100W, 220 V Which one of them has higher resistance ?

If two bulbs of 25 W and 100 W rated at 220 V are connected in series across a 440 V supply, will both the bulbs fuse ? If not which one ?

An electric bulb is rated 60 W , 220 V . The resistance of its filament is
