Unformatted text preview: Univ. of Ontario Institute of Technology Faculty of Engineering and Applied Science ' & Definitions Ideal Voltage Sources: provides a prescribed voltage across its terminals irrespective of the current flowing through it. The amount of current is determined by the circuit connected to it. Electric Circuits (ENGR2790U) 50 of 310 Definitions ' & Ideal Current Sources: provides a prescribed current flow to any circuit connected to its terminals irrespective of the voltage across its terminals. The voltage generated by the source is determined by the circuit connected to it. Electric Circuits (ENGR2790U) 51 of 310 Definitions ' & Dependent (controlled) Source: its output (voltage or current) is a function of some other voltage or current in a circuit. i x and v x can be current and voltage in the circuit, respectively. Electric Circuits (ENGR2790U) 52 of 310 Definitions ' & Branch: is any portion of a circuit with two terminals. connected to it. Can consists of one or more circuit elements. So, any circuit element with two terminals connected to it is a branch. Electric Circuits (ENGR2790U) 53 of 310 Definitions ' & Node: is junction of two or more branches Supernode: encloses more than one node. Electric Circuits (ENGR2790U) 54 of 310 Definitions ' & Loop: is any closed connection of branches. Electric Circuits (ENGR2790U) 55 of 310 Definitions ' & Mesh: is a loop that does not contain any other loop. Network Analysis: determining the unknown branch currents and node voltages. Electric Circuits (ENGR2790U) 56 of 310 Univ. of Ontario Institute of Technology Faculty of Engineering and Applied Science ' & Kirchhoffs Current Law (KCL) Charge: is fundamental electric quantity. The smallest amount of charge that exists, is the charge carried by an electron: q e =- 1 . 602 10- 19 ( C ) Proton is another charge carrying particle in atom: q p = +1 . 602 10- 19 ( C ) Electric Circuits (ENGR2790U) 57 of 310 Kirchhoffs Current Law (KCL)...
