UNIVERSITY CIRCUIT I LAB EEL 3111L FORMAL REPORT #2 Based On: EXPERIMENT #5 INSTRUCTOR: XXXXXXX I. ABSTRACT The following experiment confirms the validity of the Superposition Theorem. In the experiment in order to acquire the results by means of mathematically deriving them‚ one must use not only the Superposition Theorem but also Nodal Analysis and Current Division to get the same results as getting them experimentally. II. INTRODUCTION The idea behind the Superposition

of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of better description and explanation. Say V = 5V‚ R= 1 Ω and

DE SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include

A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

Types of DC Motors and DC Generators MOTORS – convert electrical energy to mechanical energy Motors and generators are the most frequent used electrical machines. ❖ Generators action can take place when and only when‚ there is a relative motion between conducting wires and magnetic lines of force. ❖ Electric motor is in operation when it is supplied with electrical energy and develops torque‚ that is‚ a tendency to produce rotation. ❖ In DC generator‚ the armature winding is mechanically

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

better results. Asynchronous circuits keep the assumption that signals are binary‚ but remove the assumption that time is discrete. This has several possible benefits: No clock skew - Clock skew is the difference in arrival times of the clock signal at different parts of the circuit. Since asynchronous circuits by definition have no globally distributed clock‚ there is no need to worry about clock skew. In contrast‚ synchronous systems often slow down their circuits to accommodate the skew. As feature

AC Motors vs DC Motors DC Motors Prof. Dr. M. Zahurul Haq zahurul@me.buet.ac.bd http://teacher.buet.ac.bd/zahurul/ Department of Mechanical Engineering Bangladesh University of Engineering & Technology e316.eps ME 475: Mechatronics AC motors are smaller in size‚ reliable and less costly. AC motors run at fixed speed set by the line frequency. Easy speed‚ torque & direction controls in DC motors. DC motors are generally operate at lower voltages which makes these easier to interface with control

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
