an alternating current (AC)‚ the flow of charge carriers reverses direction periodically. The number of complete AC cycles per second is the frequency‚ which is measured in hertz. An example of pure DC is the current produced by an electrochemical cell. The output of a power-supply rectifier‚ prior to filtering‚ is an example of pulsating DC. The output of common utility outlets is AC. Current per unit cross-sectional area is known as current density. It is expressed in amperes per square meter

induced voltage region and determine the average voltage. What is the average voltage of the first peak? Is it induced emf? Average voltage- sum of V9526-> 533)/8 =2.194/8= 0.274 It is induced emf at this first peak because as a whole the graph presents as a sin graph which is a characteristic illustration of induced emf. 3. Why is the sign of the second voltage peak opposite to the sign of the first peak? The sign of the second voltage peak is opposite to the sign of the first voltage peak because

Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be

1. INTRODUCTION A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight‚ while the term photovoltaic cell is used when the light source is unspecified.”Photovoltaics” the field of technology and research related to the application of solar cells in producing electricity for practical use.

Voltage: Ohm ’s Law and Kirchhoff ’s Rules ABSTRACT Ohm ’s Law and Kirchhoff ’s rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohm ’s Law‚ voltage is simply proportional to current as illustrated in the proportionality‚ V=RI. As shown in this relation‚ V represent voltage which is the potential difference across the two ends of a electrical conductor and between

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically

CHAPTER 1 INTRODUCTION A. Background of the Study Concentration has been defined as the ability to direct one’s thinking in whatever direction one would intend. Concentration plays vital roles in doing well in studies. A student has to work really hard and concentrate firmly to get concepts well in mind. All students have the ability to concentrate some of the time. But at other times students’ thoughts are scattered‚ and their minds race from one thing to another. They don’t have the ability to

The Power of Concentration By Remez Sasson When I was a child‚ I saw how a magnifying glass could burn a piece of paper‚ when the rays of the sun were focused through it. The fire could start only when the sun’s rays were concentrated to a small point. When the magnifying glass was moved too far away or too close to the paper‚ the rays were not focused enough and nothing happened. This experience describes vividly the power of concentration. This power can be described as focused attention. It

Concentration Camps in Vienna The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps‚ all of which deployed incarcerated prisoners at forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow‚ near the prewar German-Polish border in Upper Silesia‚ an area that Nazi Germany annexed in 1939 after invading and conquering Poland. The SS authorities
