current very easily. Resistance An electron travelling through the wires and loads of the external circuit encounters resistance. Resistance is the hindrance to the flow of charge. For an electron, the journey from terminal to terminal is not a direct route. Rather, it is a zigzag path which results from countless collisions with fixed atoms within the conducting material. The electrons encounter resistance - a hindrance to their movement. While the electric potential difference established…
Epistemology and Contemporary Methodologies in English teaching Characterized by frequent change and innovation, the foundation of contemporary language teaching was developed during the early part of the twentieth century, as applied linguists as others pursued to build principles and procedures for the design of teaching methods and materials (RICHARDS; RODGERS, 2014, p. 1). The aim of the present text is to walk through the changes in language teaching through the methodologies, giving…
in a direct democracy each individual represents himself and can directly participate in governmental decisions without depending on an elected official. Governmental control is placed “in the hands of the people themselves”, assuming that the public is well informed to “make wise decisions on political matters, whether through referenda, town meetings, citizen initiatives, or other direct means” (Dalton, et al.). In this essay I will be discussing the positives and negatives of a direct…
site are caused by overhead or underground electrical lines." In an article by Darlene Bremer, she states "electrocutions kill an average of 143 construction workers each year. More than half of the electrocutions of electrical workers were caused by direct or indirect contact with live electrical equipment and wiring, control panels, junction boxes and transformers." According to OSHA, they estimate that there are approximately 350 electrical related deaths per year, which almost averages one…
The first of King’s four steps of a nonviolent campaign is negotiation. Before taking any sort of nonviolent direct action, negotiation must be tried first. Negotiation must be tried first because it will save people from disobedience and, as a result, the possibility of going to jail. If negotiation fails, nonviolent direct action must be done. In comparison to negotiation, nonviolent direct action is more efficient and effective because it causes tension and a crisis. The four steps of King’s…
Novel 3-Phase Single stage boost inverter: Analysis, Design and Experimentation M K Pathak, Member, Dogga Raveendhra and Aravind Panda Abstract— this paper introduces a novel type of 3-phase single stage dc-ac converter, which is controlled by sliding mode control, offers intrinsic step up abilities. Proposed inverter is designed with lesser number of solid state semiconductor switches and small passive elements. Sliding mode controller (robust controller) is designed to control this power…

In test system-II, primarily a two area multi source power system is considered with three GENCOs and two DISCOs in each area is shown in Fig. 8. The control area 1 and control area 2 comprises of reheat thermal, hydro and gas power system with the inclusion of non-linearities such as boiler dynamics, time delay (TD), governor dead band (GDB) and generation rate constraint (GRC). Boiler dynamics configuration is incorporated in thermal plants to generate steam under pressure. Changes in the…
3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…
