Course content
3 sections • 29 lectures • 2h 1m total length
- Electric Current and Voltage3:53
Describe how a potential difference drives current, illustrated with water levels in two buckets and a battery, and define voltage, emf, and current in simple terms.
- Electrical Circuits and Elements4:05
Explore electrical circuits and circuit elements, including dc and ac circuits, passive elements such as resistor, inductor, and capacitor, and active elements like voltage and current sources.
- Resistor3:18
Explore how a resistor operates as a passive two-terminal element that converts energy to heat, resists current, and is described by resistance in ohms and conductance in siemens.
- Introduction to Inductor3:55
Learn how an inductor stores magnetic energy, produces back emf that opposes current, and how inductance L relates flux, turns, and current.
- Inductor Behaviour in DC5:18
Observe how an inductor in DC opposes rapid current changes with back emf. It stores energy in a magnetic field and ends as a short circuit at steady state.
- Introduction to Capacitor2:14
Learn how a capacitor, a two-plate device with a dielectric, stores energy in an electric field and defines q = C V and current as the rate of charge change.
- Capacitor Behaviour in DC4:26
During DC, a capacitor charges from an uncharged state, stores energy in the electric field, and when fully charged becomes an open circuit that blocks current.
- Kirchhoff Laws4:51
Explore Kirchhoff's laws, including Kirchhoff's current law and Kirchhoff's voltage law, to analyze currents and voltages in circuits using node and loop concepts and sign conventions.
- Energy Sources5:55
Explore energy sources as devices that generate electrical energy. Distinguish independent sources (ideal and practical voltage and current sources) from dependent sources such as voltage-controlled and current-controlled types.
- Introduction to Network Theorems4:09
Master network theorems and reduction techniques that simplify complex networks into equivalent circuits. Learn Norton’s theorem and the superposition theorem and their role in network reduction.
- Thevenin's Theorem2:54
Apply Thevenin's theorem to convert a linear bilateral circuit into a Vth in series with Rth, using open circuit voltage and short circuit current to determine current in a branch.
- Norton and Superposition Theorem4:36
Apply Norton's theorem and the superposition principle to analyze linear bilateral circuits. Find branch currents and voltages using short-circuit and open-circuit concepts.
- Representation of AC Waveforms4:53
Learn why ac powers distribution, its sine-wave representations, and the key terms cycle, period, and frequency, including sine, square, and triangular waveforms.
- Peak and Average Value4:06
Peak value is the maximum amplitude of an alternating quantity at 90 degrees (VM); the average value over a symmetrical sine is zero, yet half-cycle analysis yields VM/π (≈0.637 VM).
- Root Mean Square (RMS) Value4:04
Learn how root mean square value provides a single, comparable measure for AC voltage or current by squaring, averaging, and taking the square root to match DC power.
- Phasor Representation3:53
Explore phasor representation of alternating quantities as rotating vectors encoding magnitude, phase angle, and frequency. See how phasors depict sine wave forms and relate voltage and current in AC analysis.
- Phasor Representation of R, L, C4:56
Explore phaser diagrams to understand phase differences between alternating quantities of the same frequency, including leading, lagging, and in-phase conditions, and apply them to resistor, capacitor, and inductor behavior.
- Real, Reactive and Apparent Power5:13
Understand real, reactive, and apparent power within the power system, from resistive and inductive loads to P, Q, and S, and their relationships via the power triangle.
- Power Factor3:58
Explore power factor and distinguish active power from reactive power in residential and industrial inductive loads. See magnetizing and working currents form apparent power, and power factor indicates efficiency.
- Three Phase Balanced Circuits6:00
Explore three-phase balanced circuits, defining balanced polyphase systems with 120-degree phase displacement, and compare star and delta connections.
- Voltage & Current Relations in Star & Delta4:26
Discover voltage and current relations in star and delta three-phase connections, derive phase and line voltages and currents using phasor representation and vector addition, including the neutral and line terminals.
- Introduction to Transformers3:23
Explore how electricity is transmitted from plants to homes, showing how high voltage and reduced current minimize losses, and how transformers step voltage for distribution.
- Faraday's Law of ElectroMagnetic Induction2:42
Move a bar magnet toward or away from a coil to induce voltage and current, illustrating Faraday's law of electromagnetic induction and its use in motors, generators, and transformers.
- Transformer Operating Principle4:16
Explore the transformer operating principle, including self and mutual induction, Faraday's law, magnetic flux in a shared iron core, and how primary and secondary windings regulate flux and load.
- Transformer Construction2:18
Explore transformer construction, featuring a laminated core with e l i sheets and two insulated windings—the primary and secondary—mounted in a tank with oil cooling to enable different voltage levels.
- Types of Transformers4:20
Explore core type and shell type transformers, including winding arrangement, insulation, and leakage flux. Compare step up vs step down, single phase vs three phase, and cooling methods.
- Ideal Transformer4:16
Explore ideal transformer concepts that enable lossless power transfer. Discover zero resistance, zero leakage flux, infinite core permeability, and how turns ratio sets voltage and current transformation.
- Practical Transformer5:55
Explore the practical transformer, including core losses from hysteresis and eddy currents, copper losses in windings, and the impact of leakage flux and leakage reactances on efficiency.
- Auto Transformer3:46
Explore the auto transformer, a single winding with taps that enable step-up or step-down operation, delivering the same voltage–current ratio with copper savings.
