RLC Resonance
Estimate the resonant frequency of an LC tank.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.

The antenna feeds a tuned LC circuit, then a diode detector extracts audio for the earpiece.

TP3: detector audio
Diagrams are simplified learning models for low-voltage electronics. They are not wiring instructions for mains, switchboards, fixed wiring, or legal electrical work.
Formula notes
f = 1 / (2pi sqrt(LC))
Great for filters and radio ideas. Real parts have tolerance, resistance, and parasitic effects.

Frequency decides which parts of a signal pass easily and which parts get reduced.

1. Estimate
Load the example or enter a real low-voltage learning value.
2. Visualise
Use the diagram to connect the formula to current path, timing, frequency, or energy flow.
3. Verify safely
Build only suitable low-voltage circuits and confirm with a meter before scaling up.
