electrical circuit theory

Electrical circuit theory explains how electric current flows through a pathway made of interconnected components like wires, batteries, and resistors. Voltage acts as the push that drives current, while resistance opposes that flow. Circuits can be arranged in series (one path) or parallel (multiple paths), influencing how voltage and current distribute. Understanding these relationships helps design and troubleshoot electronics, ensuring devices work efficiently and safely. Think of it like a water system: voltage is the pressure, current is the flow, and resistance is the pipe’s obstruction. This foundational theory guides the creation and analysis of all electronic devices.
