Explanation:
the Marked 100 watt and 220 volts is known as power rating which tells us that when a bulb is supplied with 220 volts of current it would give hundred words of power it also gives us hidden information like resistance and Maximum current
power =Current* potential difference
w=i*v
energy= power into time
=100w*2hr
=100*60*60*2
=100*7200
=720000 joules of energy...
how long will it take for the bulb to consume is not completed...
mark me as the brainliest as it takes a lot time
