This section shows main aspects of the module 108SE : Electrical Science

The module aims to provide a broad basic introduction to electrical science for non-specialists. It places an emphasis on dc circuit theory, electrical supply and rotating machinery.

The intended learning outcomes are that on completion of this module the student should be able to:

1. Employ the basic laws and analysis techniques of dc, single-phase and three-phase electrical systems.

2. Identify the requirements of various standard electrical systems and predict their performance.

3. Apply the fundamental laws of electromagnetism to transformers, motors, generators, and solenoids.

- Electrical quantities: resistance, inductance, capacitance, current, voltage, power, energy.

- Circuit theorems & analysis: Linearity, Ohm's law, Kirchoff's laws, application to dc circuits.

- Periodic waveforms, peak, mean and rms values.

- Simple phasor diagrams, power in ac circuits.

- Three-phase sources, balanced three-phase star connected loads.

- Magnetic fields: flux density, field strength, magnetic materials, permanent magnets, electromagnetism, Ampere's law, forces in magnetic systems.

- Energy storage: secondary batteries, fuel cells, capacitors and inductors. Common secondary battery technologies and their characteristics.

- Electromagnetic induction, the ideal transformer, forces on a conductor. Operation of a dc machine, 3 phase induction motor, synchronous machines. Generation of voltage.
