Soft Pre-requisite: PHY112
Fundamental electrical concepts and measuring units of electrical charge, voltage, current, resistance, and power; Laws of electricity (Ohm's law, Kirchhoff's Current and Voltage law) and various methods of electrical circuit analysis (Nodal, Mesh); Introduction to basic electrical circuit elements; I-V characteristics; Circuit analysis in Direct current, First-order Transient and Alternating current mode, for various combinations of Resistive, Inductive and Capacitive networks; Phasor representation of sinusoidal quantities; Circuit theorems for linear circuits (Source Transformation, Superposition, Thevenin, Norton and Maximum Power Transfer). This course includes compulsory 3-hour laboratory work.
The objectives of this course are to:
1. Introduce students to ideal linear electrical circuit components such as dependent and independent voltage and current sources, resistors, capacitors, and inductors and their characteristic equations.
2. Illustrate the I-V characteristics of any two-terminal devices and infer circuit equivalence.
3. Define physical quantities related to electricity such as voltage, current, and power, and introduce passive sign convention for computing these quantities.
4. Explain fundamental laws like Ohm’s law, and Kirchhoff’s voltage and current law, as well as important linear circuit theorems such as Thevenin’s and Norton’s theorem, maximum power transfer theorem, superposition principle, and source transformation.
5. Familiarize students with several circuit-solving techniques aside from the circuit theorems, such as the voltage/current divider rule, series-parallel circuit equivalence, and nodal and mesh analysis, that take advantage of the fundamental laws and theorems of the linear circuit.
6. Analyze first-order transient circuits with resistors, capacitors, and inductors in the time domain.
7. Introduce phasors and analyze alternating current (AC) circuits constructed from sinusoidal sources, resistors, capacitors, and inductors in the phasor domain.
