Answer :
In a pure RLC circuit, resonance can indeed occur. Let's break this down step-by-step to understand why:
What is an RLC Circuit?
An RLC circuit is an electrical circuit consisting of three components:
- R: Resistor, which resists the flow of current and dissipates energy as heat.
- L: Inductor, which stores energy in a magnetic field when current flows through it.
- C: Capacitor, which stores energy in an electric field.
What is Resonance?
Resonance in an RLC circuit occurs when the circuit is driven by an external force (like an alternating current supply) and the frequency of this driving force matches the natural frequency of the circuit. This causes the circuit to oscillate with maximum amplitude.
How Does Resonance Occur in an RLC Circuit?
The natural frequency, often called the resonant frequency, [tex]f_0[/tex], is given by the formula:
[tex]f_0 = \frac{1}{2\pi \sqrt{LC}}[/tex]
This frequency is dependent on both the inductor [tex]L[/tex] and the capacitor [tex]C[/tex]. At this frequency, the reactance of the inductor and the capacitor cancel each other out.
At resonance, the impedance of the circuit is minimized and equals the resistance [tex]R[/tex] alone, allowing the circuit to draw maximum power.
Because the inductive and capacitive reactances are equal and opposite, they effectively 'cancel' each other, meaning the circuit becomes purely resistive at this frequency.
Why is Resonance Important?
- Resonance is used in various applications, such as tuning radios to pick up specific frequencies.
- It's also crucial in designing filters and oscillators in electronic circuits.
So, to answer the question: Is resonance occurring in a pure RLC circuit? The answer is True. At the resonant frequency, the conditions for resonance are met in a pure RLC circuit.
