Common light bulbs are designed for use with120 V and are rated by the power dissipated as heat and light.
a. What is the resistance of a 40W bulb?
b. What is the resistance of a 60 W bulb?
c. If the 40 W bulb is connected in serieswith the 60 W bulb and 120V is applied across the combination, then what is the power dissipated ineach?
