Hey guys I am having some trouble with this simple questions:
What is the resistance of a light bulb that uses an average power of 75.0 W when connected to a 60.0 Hz power source having a maximum voltage of 190 V?
(b) What is the resistance of a 120 W bulb?
I tried doing it by (75/190)^2 * (2pi60) but this is not correct.
