23see,
consider an equipment of 100 watts
now the formula that we hav Power = i2R
is related to heat
now it depends on the equipment
100 watts = power related to heat+ power related to its mechanism
( though i m not sure [3] [3] lol)

1yeah answer is wrong!!!!!!!
answer this question guys::
an instrument X n Y are marked as 100 W n 220 V and 100 W n 220 V respectively.the resistance of X is
(a)greater thn y
(b)equal to Y
(c)less than y
(d)zero
P.S. X n Y cn be anything LOL!!!!!!!!!!.ranging from heater to anything in the world!!![3][3][3]...now answer me[1]
231@qwerty...
well i don happen to agree[2][2]..at constant potential difference instruments of same power rating offer equal resistance!
23wasnt sure of my logic and hence termed it as a wild guess [4]
see take a bulb and a tubelight of same watts , bulb become more hot than the tubelight bcz the tungsten filament has considerable resistance
in this question, think conversely
1Higher the resistance, more heat will be produced...and thats exactly the function of a heater. Fan does not produce high amt. of heat.
23formula use kiya t C hi a raha hai , but i feel there is something else in this question [4]
