Question

Two electric bulbs are rated 60 what does 220 volt and hundred what does 220 volt respectively both are connected in series to supply air volt of 220 calculate the current flowing in the world

Answer 1

We know the formula of Power

Power=voltage*current

when 2 bulbs are connected in series then current will flow throughout the path will be same so in both bulbs of 60 watt and 100 watt, current is same.

but the resistance in 60 watt is more so that brightness is also more as compare to bulb of 100 watt.
