Ideal Op Amp Circuits The operational amplifier‚ or op amp as it is commonly called‚ is a fundamental active element of analog circuit design. It is most commonly used in amplifier and analog signal processing circuits in the frequency band from 0 to 100 kHz. High-frequency op amps are used in applications that require a bandwidth into the MHz range. The first op amps were vacuum-tube circuits which were developed for use in analog computers. Modern op amps are fabricated as integrated circuits

CHAPTER 1 1.0 INTRODUCTION Students’ Industrial Work Experience Scheme (SIWES) is a skill development program designed to prepare students of Universities‚ Polytechnics/monotechnics and colleges of education for transition from the college environment to work (Akerejola 2008). Oyedele (1990) state that work experience is an educational program in which students participate in work activities while attending school. 1.1 brief histories of SIWES The Students’ Industrial Work Experience Scheme (SIWES)

between conductors by using the configurations and conductor values given for each line segment. These results provide the information needed to create the primitive impedance matrix‚ Zprim. Using the matrix operation known as Kron reduction‚ shown in Equation (1) below‚ these primitive matrices can be converted into Zabc impedance matrices. Z=A-BC^(-1) D (1) Each matrix can then be multiplied by its respective segment length to convert to actual ohmic values of line resistance. These matrices

that we can replace entire network by an equivalent circuit that contains only an independent voltage source in series with an impedance (resistor) such that the current-voltage relationship at the load is unchanged. Norton’s Thereom is identical to Thevenin’s Theorem except that the equivalent circuit is an independent current source in parallel with an impedance (resistor). Therefore‚ the Norton equivalent circuit is a source transformation of the Thevenin equivalent circuit Note: When

&CHAPTER 7 Power Flow Analysis 7.1 INTRODUCTION Power flow analysis is concerned with describing the operating state of an entire power system‚ by which we mean a network of generators‚ transmission lines‚ and loads that could represent an area as small as a municipality or as large as several states. Given certain known quantities—typically‚ the amount of power generated and consumed at different locations—power flow analysis allows one to determine other quantities. The most important

one type of configuration‚ it can be easily transformed or changed it into an equivalent configuration of the other type by using either the Star Delta Transformation or Delta Star Transformation process. A resistive network consisting of three impedances can be connected together to form a T or "Tee" configuration but the network can also be redrawn to form a Star or Υ type network as shown below. T-connected and Equivalent Star Network As we have already seen‚ we can redraw the T resistor network
