[QUOTE="semistudent, post: 5497611, member: 596753"] Tv set is an example You are supplied with 10 amperes Your tv needs 2 ampere Why can not your tv draw current more than 2 amper? If you say because ohm law , this law say that resistance resist current flow This mean the resistor of your tv set will permit flow of only 2 ampers The remaining which is 8 amperes will be prevented by resistor and converted to heat So all the 10 should be consumed by the tv set The tv is an example My question is more general Why the devices does not draw all the available current?
