Hi
if i have a voltage supply of 100V connected across a 66 ohm resistor which has a power rating of 155W. then P=V^2/R=10000/66=151W but say if i had the same situation except i add another resistor in series to increase the resistance of the overall circuit by adding a 100 ohm resistor which has a power ratting of 1W. then P=10000/166=60W.
but the question i have is will the 100 ohm resistor blow up because there is 60W across both resistors as it has a power rating of 1W?
