Based on the conservation of charge, it states that the total current entering a node must equal the total current leaving it.

Components are connected end-to-end. The current is the same through all components, but the total voltage is divided among them. (

While Ohm's Law handles individual components, Kirchhoff’s Laws handle how they interact in a network.

Based on the conservation of energy, it states that the algebraic sum of all voltages around any closed loop in a circuit must be zero. 5. Series vs. Parallel Circuits How components are connected changes the math:

): The actual rate of flow of electric charge. Think of it like the volume of water flowing through a pipe. It is measured in . Resistance (

Electrical circuit analysis is the mathematical foundation of electrical engineering. It provides the tools to predict how energy moves through a system of interconnected components. Whether you're looking at a smartphone or a power grid, the same core principles apply. 1. The Fundamental Quantities

Circuits are made of components (which provide energy, like batteries or generators) and Passive components (which consume or store energy, like resistors, capacitors, and inductors). Nodes: Any point where two or more components meet.
