1)Problem 12-2: Find AC collector resistance and AC saturation current of fig 12-38. Soln: In the AC equivalent circuit we have Rc || R(Load).As such the Ac resistance = ((680*2700)/(680+2700)) ohm=543 ohm. The Voltage at base of transistor=(470*15)/(470+2000)=2.85V.Drop across Base emitter=0.7V. Hence Ve=2.85-0.7=2.15 V. hence IE= (2.15/220)A=9.7 ma.Since Ie appx equal to Ic hence AC saturation current = 9.7 ma. 2)Problem 12-6 DC collector resistance and DC saturation current of Fig 12-39 Soln:

Jason Haas Research paper 1 Mr. Smith unit 4 a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted. A bus is the path through which a device sends its data so that it can communicate with the CPU and or other devices. There are traditionally three different types of buses found on a mother board which are the front side bus (F.S.B) which can be explained as being the interface

GS1145 Electric circuits My field of study is Electrical Engineering Technology, associate’s degree, and I’m planning on continuing to my bachelor’s degree. As the title says, the new technology in my field of study that I want to know more about is electric circuits. I learned that, “A circuit is an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end,” (Electric Circuits, 2012). In the article it is also stated that the marble-and-hula-hoop

Arguments about Computer dependency Since their invention, people far and wide have become increasingly dependent on computers. Computers have found their way into just about every aspect of our lives, and in most cases, they make things easier for us [4] . They allow us to work from home, socialize with our friends and family who live too far away to visit, and they provide an ever-welcome stress relief when we come home from school or work and just want to have some fun. But as we increasingly
