yeah 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]

see,
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)

@qwerty...
well i don happen to agree[2][2]..at constant potential difference instruments of same power rating offer equal resistance!

yup , actually same logic as guruji [1]

wasnt 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

is it b ??? giving a wild guess [5]

Higher the resistance, more heat will be produced...and thats exactly the function of a heater. Fan does not produce high amt. of heat.

No explanation was given,and even my initial impulse was to mark 'C'.
