To evaluate the transient response of an RC circuit, you start with the steady state just prior to the transient, i.e. just prior to the switch being opened or closed, or just prior to whatever transient event you are modeling. Since you are steady state, assume that capacitors are not present, i.e. they are resistors with infinite impedance. Calculate the voltage and current at each node, using Ohm's law and/or Kirchoff's law and/or Norton/Thevanin equivalents as necessary. Remember that capacitors resist a change in voltage. The equation is dv/dt = i/c. At t=0, assume that each capacitor has the voltage calculated from the initial steady state condition. Initiate the transient and calculate the voltage and current at each node using the initial state differential equation. You can do this analytically, or you can model it in software. If you model, pick an appropriate delta-T, and do a step wise evaluation until the voltages and current settle to their new values. Adjust delta-T to make sure that you are getting consistent results. Just don't go too short, as truncation error can bias the results.

What component limits current in a circuit?

A resistor or an inductor. The inductor limits transient current, not steady state current.


What do you mean by steady state reactance?

If you use AC components (i.e. inductor or capacitor ) on DC circuit, they will initially behave different than at steady state. Steady state is the state in which the behavior is not changing with time. (theoretically after infinite time, practically within small time any ckt reaches steady state)


AC operation of magnetic circuit?

DC sources are not used for excitation of magnetic circuit of transformers and other AC machines. AC sources are used. The steady-state current is calculated by the applied voltage and resistance of the circuit when DC excitation is applied. The inductance in this case plays the role only for the transient part. The adjustment of the magnetic flux takes place as per the value of current to satisfy the relationship of B-H curve or magnetization curve. For the case of AC excitation, inductance comes into picture for steady-state performance. The flux is determined by the impressed voltage and frequency. The adjustment of magnetization current takes place as per the value of this flux to maintain the relationship imposed by the magnetization ....


What happens when a capacitor reaches a steady state?

when a capacitor reaches it, it acts as a battery


Compare synchronous and asynchronous operation of sequential circuits?

A Synchronous Sequential Circuit is a system whose behavior can be defined on the timing of their signals , where in the case of asynchronous sequential circuit depend upon the order in which its inputs signals change and can be affected at any instance of time . (reference : M. Moris Mano)

What is meaning for transient in RLC series circuit?

In circuit analysis, there is steady state and transient conditions. transient conditions are how the circuit acts immediately following some action (such as turning on power, closing a switch, losing power, etc.). Steady state conditions is everything else.

How does transient heat transfer differ from steady state heat transfer?

In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.

What is environment to you?

Environment is the set of physical conditions surrounding a given object. It can be steady-state or transient.


What is transient voltage?

A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.


What is subtransient current?

Transients -- they can be currents or voltages -- occur momentarily and fleetingly in response to a stimulus or change in the equilibrium of a circuit. Transients frequently occur when power is applied to or removed from a circuit, because of expanding or collapsing magnetic fields in inductors or the charging or discharging of capacitors.


How can you find the steady state current in RLC series circuit?

-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.


Difference between steady state and transient analysis?

In steady state analysis, you assume anything that changes with time is 0. ie: d*rho/dt = 0. In transient, you keep all your d/dt terms. Steady state simplification is a handy tool to make many differential equations solvable, by reducing their "dimension", as x-direction, y-direction, z-direction, and time are each dimensions.


What Is transient time?

Transient time refers to the period it takes for a system to reach a stable state after a change or disturbance. It is the time it takes for a system to settle down and for its outputs to stabilize after a varying input. In electrical engineering, transient time can refer to the time it takes for a signal to reach a steady state after a change in inputs or conditions.

What is inductor functioning?

Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....
