Understanding Characteristics of RLC Circuits

AI Thread Summary
Characteristic frequency in RLC circuits refers to the natural frequency at which the circuit oscillates when not damped. The damping ratio indicates how oscillations in the circuit decay over time, with overdamped circuits returning to equilibrium slowly, underdamped circuits oscillating before settling, and critically damped circuits returning to equilibrium as quickly as possible without oscillating. To achieve specific damping conditions, one must adjust the values of resistance (R), inductance (L), and capacitance (C) in the circuit. The method involves calculating the damping ratio using the formula based on these component values. Understanding these concepts is essential for analyzing the behavior of RLC circuits in various applications.

speaking of R-L-C series and parallel circuits, can anyone tell me what is the physical meaning of characteristic frequency, damping ratio, overdamped, underdamped, critically damped circuits?

Welcome to the PF.

Have a read through this introductory page, and if you have a specific question, ask it here.

http://en.wikipedia.org/wiki/RLC_circuit

Remember that we cannot do your schoolwork for you, according to the PF rules. But if you are confused about a specific concept, we may be able to help.
 
You might also want to compare and contrast RLC with a mechanical spring or pendulum...
Then, as they say, come back with specific questions.

well thanks but i was confused in concept especially of characteristic frequency. we solve several numericals in course and derive many formulas, but still cofusion remains; how to explain these terms in physical meanings??
 
i got a question. how to determine value of L and C in series RLC circuit to make it underdamped, overdamped and critically damped? just want to know the method to find its values.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
