Electricity: Direct Currents

Instructor: Ray F. Valenzuela

Semester: Fall '99

Room: 412 (SSHS)

Course Description: This is the first major course in fundamentals of electricity. It is designed to teach the student the basic electricity and electronics covering the following areas: Electricity, Ohm's Law, Series Circuits, Parallel Circuits, Series Parallel Circuits, R esistors, Voltage Divider and Current Dividers, Direct Current Meters, Kirchhoff's Law, Network Theorems, Conductors and Insulators, Batteries, Magnetism, Magnetic Units, and Electromagnetic Induction.

Course Objectives:1. Solve basic problems involving current, voltage, resistance, and power. 2. Using a schematic diagram as a guide, construct dc circuits with components such as resistors, relays, seitches, lamps, batteries, and capacitors. 3. Use a multimeter to measure current, voltage, and resistance. 4. Explain the relationship between current, voltage, resistance, and power. 5. Describe the construction, operation, and purpose of resistor, potentiometer, seitches, fuses, capacitors, inductors, batteries, and relays. 6. Build and experiment with basic dc circuits of your own design. 7. To know the proper procedures in solving dc circuits such as series, parallel, and series-parallel circuits. 8, To know the procedures in solving dc circuits using Kirchoff's Law, Thevenin Theorems, supposition Theorem, Norton's Theorem and Millman's theorem.

Course Activities: 1. Lectures and demonstration. 2. Laboratory experiment. 3. Project Construction

Performance Criteria and Evaluation: 1. Students are required to observe all safety rules and regulation inside and outside the electronics shop area. They are also expected to attend classes regularly and promptly, work on their assignments, lab experiments, participate and provide meaningful discussion. 2. Evaluation will be based upon the attainment of the competencies and learning outcomes established for the course, with thirty percent of the grade being determined by performance if hands on task in the laboratory.
