is current wasted in a resistor if no then why??

Answers

Answered by DarkNinjagaming

If you are using the resistor to limit current, and it is dissipating a significant amount of power, that is a waste of energy, and it may result in a significant cost for a heat sink, and maybe even a fan. ... Modern fluorescent lamps use electronic switching ballasts which waste even less energy.
