Resonant Frequency vs Inductance
सूत्र
## LC Resonant Frequency An LC circuit oscillates at a natural frequency determined by the inductance and capacitance. ### Formula **f = 1 / (2*pi*sqrt(L*C))** At resonance, the inductive and capacitive reactances are equal and cancel, leaving only resistance to limit current.
हल किया गया उदाहरण
An LC circuit with L = 10 mH and C = 100 μF.
- 01f = 1 / (2*pi*sqrt(L*C))
- 02f = 1 / (2*pi*sqrt(10e-3 * 100e-6))
- 03f = 1 / (2*pi*sqrt(1e-6))
- 04f = 1 / (2*pi*0.001)
- 05f = 1 / 0.006283 = 159.15 Hz
अक्सर पूछे जाने वाले प्रश्न
What is resonance in an LC circuit?
Resonance occurs when the inductor and capacitor exchange energy back and forth at a natural frequency, like a pendulum swinging.
Where are LC circuits used?
In radio tuners (selecting a station frequency), oscillators, filters, and impedance matching networks.
What limits the oscillation in a real LC circuit?
Resistance in the wire and components gradually converts the oscillating energy to heat, causing the oscillation to decay (damped oscillation).
