Theory
Electrical theory is the foundational understanding of how electricity works, encompassing the principles that govern the behavior of electrons in circuits. It delves into concepts like voltage (electrical pressure), current (the flow of electrons), and resistance (opposition to flow), explaining their interrelationships through laws such as Ohm's Law. This theoretical framework is crucial for anyone working with electricity, as it provides the basis for designing, analyzing, and troubleshooting electrical systems, from simple household wiring to complex industrial power grids.
