This tutorial presents an overview of the concept of Parallel Resonant Frequency, a key principle in the field of electrical engineering and physics. This topic centers on the relationships and calculations related to the value of a capacitor and inductance. Understanding this principle is critical in designing and analyzing electric circuits, particularly those involving alternating current (AC).

The resonant frequency formula for a parallel LC circuit is a natural outcome of the principles of electromagnetism, specifically the laws governing inductive and capacitive reactance. Its difficult to attribute the formula to a single individual, as it has been refined over time with the progression of our understanding of electric circuits.
One practical application of parallel resonant frequency is in tuning circuits for radios and televisions. These circuits must be able to select the correct signal from the many that are broadcast simultaneously. By adjusting the resonant frequency, a device can be tuned to pick up a specific signal while ignoring others.
Oliver Heaviside, a self-taught English electrical engineer, made substantial contributions to the field of electrical circuit analysis during the late 19th century. His work greatly improved our understanding of capacitive and inductive effects in transmission lines, laying the groundwork for modern electrical circuit theory.
Understanding the principle of parallel resonant frequency and the related calculations are vital in the fields of physics and electrical engineering. These concepts have provided the basis for many technologies we rely on today, including radios, televisions, and many other electronic devices.
