Experiment 4: Damped Oscillations and Resonance in RLC Circuits Goals: An RLC circuit is a damped harmonically oscillating system, where the voltage across the capaci-tor is the oscillating quantity. In the first part of this lab, you will experiment with an underdamped RLC ... An oscilloscope will be used to measure the applied voltage ...

A circuit containing a resistor, a capacitor, and an inductor is called an RLC circuit (or LCR), as shown in Figure 1b. With a resistor present, the total electromagnetic energy is no longer constant since energy is lost via Joule heating in the resistor. The oscillations of charge, current and potential are now continuously decreasing with ...

`alpha=R/(2L)` is called the damping coefficient of the circuit `omega_0 = sqrt(1/(LC)`is the resonant frequency of the circuit. m 1 and m 2 are called the natural frequencies of the circuit. The nature of the current will depend on the relationship between R, L and C. There are three possibilities: Case 1: R 2 > 4L/C (Over-Damped)

varied and the periods of the oscillations were used to determine the inductance in ... When b2 = 0 the circuit is said to be critically damped. In this case the two roots ... Additionally a Tektronix TDS3012B oscilloscope with serial number F28819 was used to measure the transient response in all parts.

AC and TRANSIENT RESPONSE OF A RESONANT LCR CIRCUIT ... The oscilloscope can be triggered with the SYNC OUT signal from the generator and you should then observe damped harmonic oscillations in VR(t). Measure both the frequency of the oscillations ...

Experiment 11: Driven RLC Circuit OBJECTIVES 1. To measure the resonance frequency and the quality factor of a driven RLC circuit by creating a resonance (frequency response) curve. 2. To see the phase relationships between driving voltage and driven current in such a circuit at, below, and above the resonance frequency. 3.

1.1 Electrical Oscillations of an LCR Circuit Figure 1: Schematic of LCR circuit where R is the resistance, C is the capacitance, Lis the inductance, and Eis the AC emf or ‘driving voltage.’ Figure 1 shows a schematic of an LCR circuit. The equations of displace-ment for the above driven spring-mass system are an exact parallel of the

How do you define the resonance frequency of a forced damped oscillator? ... When it comes to electrical systems eg a series LCR circuit the parameter which is often measured is the current and the frequency at which current resonance occurs is the natural ... Inserting an arbitrary phase in the equation for driven damped oscillations.
