Unformatted text preview: refixes for units 8 EE1002 Introduction to Circuits and Systems Fundamentals of Electric Circuits Learning Objectives 1. 2. 3. 4. 5. Be familiar with some electrical quantities like charge (electron), voltage, current and power Learn about ideal and practical voltage and current source. Apply the passive sign convention. Learn about resistance, resistor and Ohm’s law. Calculate the power dissipated by a resistor. Definitions Charge The fundamental electrical quantity is charge. The unit of charge is Coulomb (C) and the smallest amount of charge that exists is the charge carried by an electron which equals to: qe 1.602 1019 C Electrons are the most common charge carriers. In a conductor, a large number of electrons move under the influence of an electric field giving rise to current. The other charge carriers are holes (absence of electrons) or ions. Circuit In EE, a circuit is a closed path where charge carriers move around, to carry useful information or energy from one place to another. Example: In a torch l...
