Answer / vijay

1 unit = 1kwh = 1000wh

100w = ? hours

1000wh/100w = 10h

watt and watt gets cancelled hour remains.

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

-----------means a source which can supply a constant voltage to aload irrespective of the valu of load resistance.
