Consider a house gets 110V AC supply...
Then a 60W bulb will have a resistance of 201.64 ohms and
a 100W bulb will have a resistance of 121 ohms
Inference: Lower the resistance, more is the power dissipated...
Isn't this contradicting??
I have been thought from the begining that resistance is something bad.. we make it minimum to avoid losses..
We go for copper wires because copper provides less resistance.. etc etc...
Then why on earth do we go for less resistance if more power disspates in a less resistive element...
