Answer Posted / narayana rao veeramalla
ohms law states that at constant temperature current
directly proportional to voltage and inversely to resistance
it doesn't involved any constant power concept... As the
potential you apply across the conductor increases the
current carrying electrons flow definitely increases...
here the question is for a constant power output motor...
for keeping the L.H.S constant the R.H.S two variables will
be in inversely proportionate in power equation P=VI....
