A. The current through a lamp connected across 154 V is 1.25 A when the lamp is on. What is the lamp’s resistance when it is on (and hot)? b. When the lamp is COLD, its resistance is one forth as large as it is when the lamp is hot. What is its COLD resistance?

c. Then what would the current through the lamp be just after it is turned on, when it is still cold? (Still connected to a potential difference of 154 V.)

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
