A typical lightbulb in your house is rated 150 W, which means that the bulb dissipates 150 W when connected to a DC voltage of 115 V. (a) What is the current through the lightbulb? (b) If the voltage is reduced to 40 V, what is the dissipated power?
13.7 A room has eight fluorescent fixtures. Each fixture uses three fluorescent lamps totaling 150 W in cluding the ballast. It is desired to switch on and off the center lamp of each fixture for a low level of illumination and the other two lamps by another switch for a medium level of illumination. Switch ing on all three lamps will provide the highest level The switching shall be accessible from either of the two entries to the room. The...
