Guys...it may be a silly question but i have a doubt...if voltage is high,current is low and thus,heat loss in wires is minimum,i.e.,voltage is inversely proportional to current,but potential difference is directly proportional to current (ohm's law)..how can it be??...is it because temperature is varying in first case??

A light and a heavy body have same momentum . Which will have more K.E ?

What are conduction electrons??
