How does a RLC circuit work? Are RLC circuits used in communication systems? An RLC circuit is an electrical circuit consisting of a resistor ( R), an inductor ( L), and a capacitor ( C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC. Parallel RLC Circuit Impedance: Power Factor: Resonance Frequency: When inductive reactance XL & capacitive reactance X c of the circuit is equal. Quality Factor: It is the ratio of stored energy to the energy dissipated in the circuit. Bandwidth: Resonant Circuit Current: The total current through the circuit when the circuit is at resonance. Current Magnification. Voltage and Current in RLC Circuits ÎAC emf source: “ driving frequency” f ÎIf circuit contains only R + emf source, current is simple ÎIf L and/ or C present, current is notin phase with emf ÎZ, φshown later sin( ) m iI t I mm Z ε = − = ωφ ε= εω m sin t ω= 2πf sin current amplitude( ) m iI tI mm R R ε ε = = = ω. The RLC Circuit The RLC circuit is the electrical circuit consisting of a resistor of resistance R, a coil of inductance L, a capacitor of capacitance C and a voltage source arranged in series.
Richard FeynmanOBJECTIVES To observe free and driven oscillations of an RLC circuit. THEORY The circuit of interest is shown in Fig. 1, including sine- wave sources. We start with the. What is RLC series circuit? A series RLC circuit driven by a constant current source is trivial to analyze. Since the current through each element is known, the voltage can be found in a straightforward manner. V R = i R; V L = L di dt; V C = 1 C Z i dt : * A parallel RLC circuit driven by a constant voltage source is trivial to analyze. This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction.
The result is an oscillation, or resonance. What is the quality factor in a RLC circuit?
