Understanding Characteristics of RLC Circuits

Click For 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.

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.
 
I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
