Answer / vijay

1 unit = 1kwh = 1000wh

100w = ? hours

1000wh/100w = 10h

watt and watt gets cancelled hour remains.

so it takes 10 hours for a 100 watt bulb to complete 1 unit.

Answer / shekhar

i unit=1kwh
so to complete one unit it should glow for 10 hours

Answer / balakrishnan

As per basic electricity Concept 1 unit=1000 watts or 1KWH

Now we take 100 w/h load .Its mean it will
take 100w (electricity power consumed)by one hour and
respectively 200 w take two hours.....Finaly 1000w take 10
hours (without load interuption).

So it will take 10 hours
