1) Chris is throwing a tailgate party before a nighttime football game. To light the tailgate party, he connects 15 large outdoor lamps to his 12.0-V car battery. Once connected, the lamps do not glow. An ammeter shows that the current through the lamps is 0.350 A. If the lamps require a 0.500-A current in order to work, how many lamps must Chris remove from the circuit?
2) Determine the maximum safe voltage that can be applied across three parallel resistors of 92, 150, and 220 ohms, if all three are rated 5.0 W.
