EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

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

DC to AC Inverter Assignment # 2/ Spring 2013 CE721 Ahmad Ghaffari‚ 1203840 Submit Date: Tuesday 19‚ 2013 Abstract DC-AC inverter is a device that converts a direct current (DC) into an alternating current (AC). When there is no AC main power for applications in caravans‚ remote area and etc.‚ this tool is very suitable to use. It mainly converts a DC source (like a car’s battery) to an AC source (230V) to use for power application like
