Laboratory Report Title of Experiment: Series and Parallel Circuits Date Given: January 28‚ 2013 AIM: To investigate the circuits to tell whether the resistors are in parallel or in series also to determine the internal resistance of a 1.5V cell. THEORY: In this experiment it was expected of the experimenter to have a basic knowledge of circuits in both aspects theoretically and practically. A basic circuit comprises of a cell or power supply (some electric driving force) a

TYPES OF DATA FLOW DIAGRAM: LOGICAL DFD PHYSICAL DFD Data Flow Diagrams (DFDs) are categorized as either logical or physical. A logical DFD focuses on the business and how the business operates. It describes the business events that take place and the data required and produced by each event. On the other hand‚ a physical DFD shows how the system will be implemented. Design Feature Logical Physical What the model depicts How the business operates How the system will be implemented

PART 1 MODULE 3 VENN DIAGRAMS AND SURVEY PROBLEMS EXAMPLE 1.3.1 A survey of 64 informed voters revealed the following information: 45 believe that Elvis is still alive 49 believe that they have been abducted by space aliens 42 believe both of these things 1. How many believe neither of these things? 2. How many believe Elvis is still alive but don’t believe that they have been abducted by space aliens? SOLUTION TO EXAMPLE 1.3.1 When we first read the data in this example‚ it may seem as if the numbers

Experiment 5: RC Circuits Abstract The purpose of this lab is to learn and understand RC Circuits. An RC circuit is composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching‚ because then we would only have a conductor. The insulator between the plates is also known as the dialectic‚ which affect how the capacitor will store

series with the armature circuit. This resistance is gradually reduced as the motor gains speed (and hence Eb increases) and eventually it is cut out completely when the motor has attained full speed. The value of starting resistance is generally such that starting current is limited to 1.25 to 2 times the full-load current. 5.8 Types of D.C. Motor Starters The stalling operation of a d.c. motor consists in the insertion of external resistance into the armature circuit to limit the starting current

Free Data Flow Diagrams Tutorial DFD Tutorial Data Flow Diagrams - Introduction Data flow diagrams can be used to provide a clear representation of any business function. The technique starts with an overall picture of the business and continues by analyzing each of the functional areas of interest. This analysis can be carried out to precisely the level of detail required. The technique exploits a method called top-down expansion to conduct the analysis in a targeted way. [pic] The
