We normally give \"brightest\" of a house-hold light bulb by giving the amount of power that light bulb uses. A house-hold bulb that discipates 100W of electrical power puts out more light that one that discipates 60 Watts of electrical power. A standard light bulb operates on a potential drop of around 95 V. 1) For a 75 watt light bulb, what is the current through the bulb?
i =
2) What is the resistance of this bulb?
R =
3) Now assume you have a light bulb that has half the resistance of the one in part (2) and the same potential drop. What is the is the power rating of this bulb?
P=
