Consider the circuits shown in figure 4. Each represents a configuration of LEDs driven by a voltage or a current source. For the purpose of this problem you can model the LED as a resistor. The intensity of the LED is proportional to the power dissipated by it. Suppose one LED burns out (i.e. becomes a open circuit), for each configuration shown determine if the intensity of the remaining LEDs becomes brighter, dimmer or stays the same. Support your answers with appropriate calculations. V 2000855 bbb (b) Figure 4: LEDs arranged in different configurations

2. A bank of nickel-cadmium cells is used as the emergency lighting supply for a hospital. There are 100 cells connected in series and each has an A-hr rating of 120 A-hr. The bank has to be replaced, and the manufacturer is no longer supplying nickel-cadmium cells. It is decided to replace the cells with lead-acid cells. How many lead-acid cells will be required if each has an A-hr rating of 60 A-hr, and how should they be connected?
Question 3: A very simple model for the distribution of clectricity to a typical home is shown in the figure below. Some of components labeled a, b, c, d, c, f, g and h represent the electrical source to the home, some represent the wires that carry the electrical current from the source to the devices in the home requiring electrical power, some represent lamps, televisions, hair dryers and other devices that require power. Assume you are an engineer in charge of a project and one of your subordinate engineers reports that the interconnection in the figure does not pass the power check. The data for the interconnection are given in the table below. Is the subordinate correer? Explain your answer. If the subordinate is correct, find the error in the data. Explain your answer clearly. Based on your answer identify that which label(s) used for the electrical source, wires or other devices. a e h
