This subject aims to cover the basic elements of direct current circuits. The student is familiarised with a range of components, measurement techniques and important issues surrounding electrical safety when constructing and testing DC circuits. Ohm's Law, Kirchhoff's Laws, The Principle of Superposition, Thevenin's Theorem and Mesh Current Analysis are all introduced and used to analyse circuits. The behaviour of capacitors and inductors in DC circuits is explored.
