We learned about Impedance, Kirchoff's Current Law and Kirchoff's Voltage Law. The class focused on applying Kirchhoff’s Current Law (KCL) using node analysis to determine unknown voltages or currents, where the sum of currents at any node must be zero. We also learned the definition of an electrical network, which consists of one or more branches, nodes, loops, and meshes. Additionally, two main network analysis methods were introduced: node analysis based on KCL and mesh analysis based on Kirchhoff’s Voltage Law (KVL). Although the topic was challenging due to current direction and complex circuits, practice helped improve understanding.
