In fact, they will be considered to be same point electrically. A piece of copper wire is used as the conductor to connect two elements in a circuit. Its resistance will be very small (but not zero). 21 EE1002 Introduction to Circuits and Systems Circuits (Networks) Analysis An electrical circuit contains a source (voltage or current) and other elements, with closed paths for the electrical current to move. Given a circuit, it is often required to obtain the value of the voltage, current and power in any of the elements. This is called circuit analysis. Learning objectives: 1. Identify the principal elements of electric circuits: nodes, loops, meshes, branches, and voltage and current sources. 2. Apply Kirchoff’s laws to simple electric circuits and derive the basic circuit equations. 3. Apply voltage divider and current divider laws to find the value of unknown variables in simple series,...
