What is the equation of LCR circuit?
Derivation of AC Voltage Applied to Series LCR Circuit In order to determine the instantaneous current or the phase of the relationship, we will follow the analytical analysis of the circuit. Here, we have substituted the value of Xc and XL by Xc = 1/ωC and XL = ω L.
What is the use of RLC circuit?
Radio receivers and television sets use them for tuning to select a narrow frequency range from ambient radio waves. In this role, the circuit is often referred to as a tuned circuit. An RLC circuit can be used as a band-pass filter, band-stop filter, low-pass filter or high-pass filter.
What is XL and XC?
Reactance is measured in ohms ( ). There are two types of reactance: capacitive reactance (Xc) and inductive reactance (XL). The total reactance (X) is the difference between the two: Total Reactance, X = XL – Xc.
What is a series RLC circuit?
Series RLC Circuit Since all these components are connected in series, the current in each element remains the same, Let VR be the voltage across resistor, R. VL be the voltage across inductor, L. VC be the voltage across capacitor, C. XL be the inductive reactance.
