Electric Circuit Theory 101

What is an Electric Circuit?

An electric circuit is a closed loop through which an electric current flows. It consists of components like resistors, capacitors, and inductors that control the flow of electricity.

Types of Electric Circuits

• Series Circuits: Components are connected end-to-end, creating a single path for current.
• Parallel Circuits: Components are connected in branches, allowing multiple paths for current flow.

Ohm's Law

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

Kirchhoff's Laws

Kirchhoff's Laws are essential in analyzing complex circuits. Kirchhoff's Current Law states that the total current entering a junction is equal to the total current leaving the junction.

Applications of Electric Circuit Theory

Electric circuit theory is crucial in various fields like electronics, power systems, and telecommunications. Understanding circuits is essential for designing and troubleshooting electrical systems.
