DC Technology & Applications - Part of Modular Certificate in Electrical & Electronic Engineering Fundamentals (DEEC1)

About This Course

The objectives of this module is to impart learners with the knowledge listed here.
1. Apply Ohm’s law to calculate voltage, current or resistance.
2. Applications: Students will be given examples of how resistance can be used from heating to measuring the stress or strain.
3. Determine the effective resistance of series circuit, parallel circuit and series-parallel circuit and analyse the current, the potential and the power dissipated.
4. Applications: Students will learn series circuits used in holiday lights, microwave oven, and safety equipment as well as parallel circuits used in car system and home wiring. The electronic circuit in a series-parallel operation will be covered.
5. Apply branch, mesh and nodal analysis to any given network of resistive elements with isolated sources.
6. Use superposition theorem to solve for current through or voltage across a specific portion of a network.
7. Find the Thevenin’s equivalent circuit and Norton’s equivalent circuit for a given portion of a network.
8. Apply maximum power transfer theorem to find RL to yield maximum power in a given network. The application in speaker’s system is covered.
9. Connect DC series, parallel, series-parallel networks and compare and contrast their characteristic.
10. Use multimeter with appropriate settings to measure resistance, voltage and current of various networks.
11. Compare and contrast the experimental results with theoretical predictions derived from some theorems.

Learners could apply skills taught here in applications where it includes how series circuits can be very effective in the design of safety equipment, and how parallel circuits configuration is done in basic household wiring.
