Hey guys I made an account here because I cannot understand this for the life of me.

Two 95 W (120V ) lightbulbs are wired in series, then the combination is connected to a 120 V supply.

How much power is dissipated by each bulb?

Answer 24W

The part I don't understand is why 95=(120^2)/R Shouldn't there be a voltage drop of 60V at each light bulb so you use (60^2) Or you could look at the equivalent resistance and use 190=(120^2)/2R ??? I cannot understand why you use the first equation for the life of me. That's saying that the power of one lightbulb is the voltage of the whole system^2 / the resistance of one bulb.

Thank you sorry for ranting this is upsetting me .
