Educational Aims
The aim of this module is to enhance students’ knowledge and concepts of electricity magnetism to enable them to pursue their undergraduate studies and to promote awareness among students of the role of physics in the universe.
Learning Outcomes
On completion of this module, the students will be able to:
explain the forces between current-carrying conductors and determine the magnetic fields generated by current-carrying conductors (wire, coil, solenoid, etc).show an understanding that the field due to a solenoid may be influenced by the presence of a ferromagnetic material.show an understanding of the concept of ferromagnetism.define magnetic flux and weber.state and use Faraday’s Law and Lenz’s Law.infer from appropriate experiments on electromagnetic induction:
(i) that a changing magnetic flux can induce an e.m.f. in a circuit,
(ii) that the direction of the induced e.m.f. opposes the change producing it,
(iii) the factors affecting the magnitude of the induced e.m.f.explain simple applications of electromagnetic induction.define and explain the phenomenon of mutual/self-inductance and show an understanding of the function of inductors in simple RL circuits.compare RC circuits and RL circuits in d.c.show an understanding and use the terms period, frequency, peak value, average value and root-mean-square value as applied to an alternating current or voltage.show an understanding of the principle of operation of a simple transformer and solve problems using turns-ratio equation.explain the half-wave and full-wave rectifications of an a.c.analyze the effect of a capacitor in smoothing the rectification of an a.c. understand the relationship between sinusoidal function and phasor, and to identify the phase relationship between R, C and L in a.c. circuits.derive the reactance of a capacitor and an inductor.use complex number system to solve problems in a.c. circuits.understand that RC and RL circuits can be used as filters in a.c. circuits.analyze a.c. circuits (series RC and RL, parallel RC and RL, series and parallel RCL) and explain resonance in a.c. circuits.calculate electrical power in passive components in a.c. circuits.apply circuit theories (KVL, KCL, superposition theorem, etc) to solve problems in a.c./d.c. circuits.understand the operational amplifier as a differential amplifier.describe ideal properties of an operational amplifier.describe the inverting amplifier and non-inverting amplifier.understand the principle of feedback in an operational amplifier.describe the use of the operational amplifier in the circuits of voltage amplifiers.
