MIT Physics Demo -- Resonant RLC Circuit

This is a simulation of an LC oscillator, which generates sinusoidal waveforms using an inductor (L) and capacitor (C) tank circuit. The oscillation occurs due to energy exchange between the inductor's magnetic field and the capacitor's electric field. Here, the frequency of oscillation is around 128 kHz, as seen in the waveform. The circuit sustains oscillations using positive feedback, and the signal is observable across the transformer’s secondary coil. #ElectronicsEducation #electronicsrd #l

This simulation shows the simulation of a damped LC oscillator circuit. It consists of an inductor (1 mH), a capacitor (1 mF), and a small resistor (100 mΩ) in series, forming an RLC circuit. When the switch is closed, energy initially stored in the capacitor starts oscillating between the inductor and capacitor. However, due to the resistor, the oscillations gradually decrease in amplitude over time, demonstrating damped harmonic oscillation. The waveform above shows voltage and current oscilla

VT1 (KT904A Transistor): The active element that acts as the oscillator and amplifier. LC Tank Circuit: The combination of L1, L2, and the variable capacitor (trimmer) C1 determines the oscillation frequency, typically within the 88–108 MHz FM broadcast band. WA1 Antenna: Radiates the modulated FM signal into the air. Resistors and Capacitors: These components set the biasing | Rizwan Khan
