The Purpose of this report is to inform one about opens and shorts in a series-parallel circuit and their effects on individual voltages (E)and currents (I).
INTRODUCTION:.
In this lab experiment, it was proven that in an open circuit, there is infinate resistance (ohms), which would limit practically all current from following the circuits path. It has also been shown that in the case of an shorted circuit, there is minimal resistance, therefore, maximun current is allowed to flow. Also, in combination curcuits, an open or a short in one branch can alter the current, resistance, and voltages throughout the remainder of he circuit. This experiment was designed to verify the following;.
1.) The charictaristics of series-parallel resistive circuits.
2.) The effects of an open scenario in a series-parallel resistive circuit.
3.) The effects of a short scenario in a series-parallel resistive circuit.
PROCEDURE:.
The procedure for this experiment is to start by measuring the individual values for each resistor used and to record them in table 18-1 (page 4). The next step was to connect the circuit shown in figur 18-3 (page 5).
SHORTS:.
1.) First, begin with calculating and the measuring the total resistance (RT or REQ) in the circuit and recordint the values in table 18-2 (page 4). Then, calculate the precentage of error and record it in table 18-2.
2.) Next, connect the circuit to your power supply and apply 15vdc. Then Calculate all voltage drops and individual component currents and record them in table 18-3 (page 4). .
3.) Then, use a voltmeter (BK Precision DMM .
2831-A) to take voltage drop measurements at each component in the circuit. Record the data in table 18-3.
4.) While keeping an applied voltage of 15vdc, remove R1 and replace with a short jumper wire. Take voltage drop measurements at all points in the circuit and record your data in table 18-3.
5.) Replae R1 and remove R2, repeat step 4 with respect to the shorted resistor.
ATHLETIC SHORTS By, Chris Crutcher The book I read this month is Athletic Shorts, it is a book full of short stories about times in teenagers lives who are in sports. The story that I am going to make into my report is the second story of the book "The Pin." Setting: Before wrestling season, lo...
Izod, polo, leg warmers, Ug boots, parachute pants, and short shorts make us think of the 1980s. ... For example, if one were to say "Name part of the lesbian uniform", most in today's culture would say things like "Birkenstocks, flannel shirt, Khaki shorts, and short hair". ... Fashion is, like never before, open to interpretation. ...
Business Description In 2002, Joe Short stumbled on an opportunity to open one of Michigan's leading craft brewing companies. ... With Scott's help, Joe was able to create the Imperial Beer Series. This series included 13 beers, made with "untraditional and unusual ingredients.... The series was released to a widespread audience, which helped Short's gain a reputation as a top tier craft brewery. ... Shorts' Future For many companies the future holds expansions and operating different and better, but not for Short's. ...
Acronyms are words created by the initial letters of a series of words; such as NASA (which is the National Aeronautics and Space Administration), Roy G. ... Acrostics are sentences that help you remember a series of letters that stand for something, like "My Very Educated Mother Just Served us Nine Pizzas- (which help you remember the order of the planets, "Please Excuse My Dear Aunt Sally- (which helps you remember the order of mathematical operations), "Never Eat Shredded Wheat- (which help remember the directions of a compass), and "May I please have a large container of orange juice?...

Series Circuit and Parallel Circuit The first thing we have to know about circuit is what a node is, its just the electrical junction between two or more components (Sparkfun Electronics). Once we understand about the node makes it half way of understand the difference between series and parallel. ... In series circuit resistance will just be RT = R1 + R2 + R3 and so on, also in series circuit current will be different compare to parallel circuit. ... On mesh analysis, I've learned how to calculate voltage, current; resistance in different nodes on series and parallel circuit mixed toget...
Over a 36-year span starting in 1930, Warner Bros. studios turned out a series of theatrical cartoons known as Looney Tunes and Merrie Melodies. ... It was clear from the beginning that instead of the jittery, head-bouncing co-star from the previous two shorts, there was a real intelligence lurking within that rabbit skin. ... Jones, who has been directing Bugs cartoons since the 1940's, added his influence to the rabbit personality in the 1950's with a series of wildly popular shorts that played Bugs as more cagey, mature and cerebral. ... Thus far, Bugs has starred in more than 175...
B) To measure the equivalent capacitance of series and parallel combinations of capacitors. ... With E=30V,R=1x10^8 Ù,C2=1x10^-6f and S1 being open while the power supply was across P1-P2. ... In part B of this experiment we were to do steps 4 and 5 which was to measure the series and parallel combination of capacitors. In part 4 of the experiment S1 was set at open and the circuit was arranged so that the capacitors C1 and C3 were in a series. ... Finally for part 5 we connected S2 to C1 and S3 to C2 while having S1 open. ...
In a series circuit, the less load, the higher the total amperage and voltage will be. ... Voltage stays the same throughout every spot in a parallel circuit. The third lab measured amperage and voltage in series and parallel circuits with two sources. ... The voltage and amperage measurements in a series circuit were higher than in a parallel circuit, which had results similar to a single source. ... If there had been no resistance in a series circuit, the voltage would be the sum of each individual load voltage, and in a parallel circuit, anywhere within the circuit would equal the tota...
All units would pull back, to reduce the risk of being struck by shorts. ... Air commanders were to instruct all pilots to attack on a path parallel to the allied ground troops. ... On this assault, all aircraft approached on a parallel course. ... He thought that they worried too much about their open flanks, which were created by the slashing attacks. Patton responded with "Forget this goddamned business of worry about our [open] flanks. ...
