(kay rap)DEFINITION OF TERMS AC (alternating current) - In electricity‚ alternating current (AC) occurs when charge carriers in a conductor or semiconductor periodically reverse their direction of movement. Household utility current in most countries is AC with a frequency of 60 hertz (60 complete cycles per second)‚ although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC. The usual waveform of an AC power circuit is a sine

generator. The shock generator had 30 lever switches ranging from 15 to 450 volts. Volunteers were presented with a sample shock (45 V) prior to the experiment‚ therefore they believed that the shock generator is real and working. The ‘learner’ started to grunt from 75 V and as the voltage went up‚ he was expressing painful groans. At 300 V he shouted that he would no longer answer and he did not provide any further noise after 330 volts. From time to time participants turned to the ‘experimenter’ for guidance

Purpose: The purpose of these experiments[1] was to measure the exciting current and determine the core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing

batteries along with the rest of the plants. The soda can version works but I haven’t tested extensively. You don’t really have to use a penny‚ just has to be copper. Perhaps other common materials would work better. Each cell gives you a useless 0.5 volts. But if you link them in series you can get more. I was able to light up an LED decently with 4 cells. Not quite as bright as Alkalines‚ but you get what you pay for I guess. While it’s probably not the easiest way to get power‚ it’s basically free

Manchester Encoding: The normal binary logics of one and zero are no more used to send data from one station to other station. The reason of not using plain binary signal is they cause ambiguities resulting in false interpretation of sent data. The major culprit is zero‚ where even no data is sent the receiver can assume it as zero. So to clear out the ambiguity or to ensure proper interpretation of data‚ a coding technique called Manchester coding is employed in IEEE802.3 standards. There are

For the analysis of GM and its environment Porter’s Five Forces will be used. This tool is primarily used to analyze the competitive environment in terms of five main categories; the threat of new entrants‚ bargaining power of both supplier and buyers‚ threat of substitute products and how intense the current rivalry is among existing competitors. In each of the five categories there are conditions/ sources that further provide insight to each; they will be analyzed in terms the car industry. This
