A wire when connected to mains supply has power dissipation Now the wire is cut into two equal pieces which are connected in parallel to the same supply. Power dissipation in this case is Then is
A wire when connected to mains supply has power dissipation Now the wire is cut into two equal pieces which are connected in parallel to the same supply. Power dissipation in this case is Then is
When wire is cut into two equal parts then power dissipated by each part is
So their parallel combination will dissipate power
Which gives
