Series resonant frequency refers to the frequency at which the reactance of an inductor equals the reactance of a capacitor, both being connected in series in an LC circuit. At this frequency, the impedance of the circuit is at its minimum and the circuit is said to be in resonance. This concept finds a substantial application in fields like electrical engineering, telecommunications, and radio broadcasting.

Resonant frequency = Hz |

The formula for series resonant frequency (f) in terms of inductance (L) and capacitance (C) is:

f = 1 / (2π × sqrt(L × C))

- f: Series resonant frequency (in hertz, Hz)
- L: Inductance of the inductor (in henries, H)
- C: Capacitance of the capacitor (in farads, F)
- π: Pi, approximately 3.14159

The formula for series resonant frequency is a fundamental result of the analysis of LC circuits, a cornerstone in electrical engineering. The development of this formula was a collective effort of many scientists over the years, with notable contributions from Michael Faraday, James Clerk Maxwell, and Oliver Heaviside.

One of the key applications of series resonant frequency is in the design of radio and television transmitters and receivers. They are used to tune to the right frequency to receive the correct channel. Also, the concept is widely used in designing various filters and oscillators in electronics.

Faraday, Maxwell, and Heaviside were the key individuals in the field of electrical engineering and electromagnetism. Their discoveries and theories set the foundation for understanding and manipulating electrical circuits, leading to many advancements in modern technology.

- Series resonant circuits are used in quartz clocks where they help to provide the precise frequency necessary for accurate timekeeping.
