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

Chapter 3 VOLTAGE SAG/SWELL MITIGATION USING DYNAMIC VOLTAGE RESTORER (DVR) 3.1 Voltage Sag Mitigation Methods Power quality problems cannot be avoided for the consumers (end users) who are directly connected together by the interconnected systems. Therefore‚ consumers must protect themselves from PQ problems with mitigation or power conditioning devices. It is researched by EPRI that 90 % of all power quality problems are voltage sags in the USA and it is assumed that the European power network

Lab# 1 The Node-Voltage Method of Circuit Analysis By: Abstract This report used KCL and Ohm’s law to calculate the node voltages and compare them to the measured node voltages after building the circuit. The calculations were obtained by hand using node analysis. The experiment was simulated on PSpice and the results were verified to hand calculations. The circuit was built in the lab and the results were measured with a digital multi-meter and compared to the calculated values‚ and

The angular speed is converted into a directly dependent voltage signals. The voltage thus generated is fed to a speedometer for speed measurement and /or used as a feedback signal for controlling the speed of a rotating shaft. An electromechanical generator is a device capable of producing electrical power from mechanical energy‚ usually the turning of a shaft. When not connected to a load resistance‚ generators will generate voltage roughly proportional to shaft speed. With precise construction

Current is a flow of electrical charge carriers‚ usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere‚ symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons

DUAL VOLTAGE DC POWER SUPPLY Supervisor: U Thein Min Wai ABSTRACT The regulated power supply converts the standard 220 volts‚ 50 or 60 Hz AC available at wall outlets into a constants DC voltage. It is one of the most common electronics circuits that we can find. The DC voltage produce by a power supply is used to power all the types of electronic circuits‚ such that television receiver‚ stereo system‚ CD players and laboratory equipment. The regulated dual voltage DC power
