Series and parallel circuits

question of why it only had a strand and not all the lights burned out lingered in my mind. It took me a few minutes before I had the aha moment when I remembered being taught about circuits in Honors Physics. I concluded that the house owners must have used lights that were in a series circuit instead of a parallel circuit. When I view the world, I tend not to see its aesthetic appeal. Instead, what I see are the science problems that need to be fixed and I think of ways to solve them.…

windshield with an assortment of protective gear, I watched the track zoom by at 25 miles per hour. Buggy is a sport unique to Carnegie Mellon University, where students from all majors join to build and compete buggies. Looking back, there are many parallels between my experience with the sport, and the development of my career aspirations. In a way, buggy was the catalyst for my interest in polymer science. Modern buggies have polyurethane wheels, which drastically reduce friction when…

classical linear narrative where strong causality linked the past with the present and future. The Bridge’s narrative was developed through a four-line structure (A: B: C: D). Each letter corresponded to a storyline. Each one of these lines function in parallel, but they did not necessarily have the same salience for the narrative or the same duration in each episode. For example, A was the most significant, B less, and so on. Some secondary storylines, for example, C, D, were often used to…

store the food like milk, buttermilk, curd, etc. If we want to store both type of food in single lunch box, we need some circuit that can produce both heating and cooling effect. The disadvantage of using this additional circuit is as following: 1. Increase in overall cost 2. Increase in total weight 3. More input power required 1.3 Aim and Objective Aim: To install a circuit in tiffin box that produce heating and cooling effect simultaneously. Objective: The followings are the objectives of…

The another advantage of this ADC is it is less complex because the DAC circuit is not used in the ADC architecture. The main drawback of this ADC is that it is only suitable for low bandwidth input signals. 4.2 Summary of ADC Architectures All the most popular ADC architectures have been explained in detail in previous sections…

Direct Current (DC) motors Name: University 1.0 Introduction A Direct Current (DC) motor is one of the broader classification of electric motors which operate from a direct current. Nearly all mechanical devices applied in daily life activities are powered by electric motors. Motors transform electrical energy to mechanical energy, hence they are essential for energy conversions in electrical machines. All types of electrical motors are made up of a stationary field referred to a stator and…

[10]. He then started working on stopper lamp that unlike Edison invention did not use vacuum. As another design modification, his bulbs are operated at low voltage for better illumination if used together. These lamps were operated in series on 110 volt circuits, resulted in higher overall efficacy compared with higher voltage lamps. Further, air was also allowed to reach the neck of the bulb thus preventing it reaching too high a temperature [11]. He devised many bases for his lamp to cope…

The year was 1878; the great inventor and scientist Thomas Edison was attempting to downsize electric lighting sources. He set out to redesign the way consumers would utilize electricity. Thomas Edison created small lightbulbs instead of the much bigger light fixtures that were in use during that time. He created small bulbs capable for indoor use, they were long-lasting, did not overheat, and above all could run on low power. A little over a year later, he patented the lightbulb using a strand…

batteries can usually push out significantly more amount of volts/amps than traditional alkaline batteries. For example, the Powerizer superior performance 3900 has 3 cells, which 2 of the cells are in series pushing 4.2 max V for each cell and a cutoff 3V per cell, which then has a third cell in parallel. However, there are several issues with the LIPO battery. First, a special battery charger is required to charge the LIPO battery once the voltage level gets low. This type of battery requires…

What does cross fit training program imply and why is it preferred? Description: Cross fit training program seems to challenge the fittest individual in the world who has to do a series of workouts without any break. Regardless of experience, a committed individual can gain a lot. Cross fit training is developed to optimize the general fitness and is dedicated to the advancement of human health and the overall athletic performance. Cross fit training program was developed by Greg Glassman…
