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)


What is insulation resistance in capacitor?

ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.


Transient and steady state response of RC circuit?

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.


Why high value resistor should be connected in series with capacitor during charging or discharging process?

A resistor is used to limit current flow through a capacitor.If you did not use the resistor, you could potentially create large currents through the capacitor, damaging it. Capacitors do have current limit ratings - check the specification sheet for the capacitor.Also, in the case of an electrolytic capacitor, if it is generally in a discharged state then it is necessary from time to time to reform it. That process involved slowly charging it, i.e. through a resistor, and then letting it discharge by itself with no or little load. The resistor protects both the capacitor and the voltage source in the case that the capacitor might be shorted.

What is the behavior of the current through a capacitor in steady state?

In steady state, the current through a capacitor is zero because the capacitor blocks the flow of direct current (DC) once it is fully charged.


What happens when a inductor reaches a steady state?

An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.


What is the behavior of an electrical circuit when a voltage source is suddenly connected, causing a current through a capacitor to flow?

When a voltage source is suddenly connected to an electrical circuit, causing a current to flow through a capacitor, the capacitor initially acts like a short circuit, allowing a large current to flow. As the capacitor charges up, the current decreases until it reaches a steady state where the capacitor is fully charged and no current flows through it.


What happens to the voltage over the inductor in the steady state as a result of Faraday's law?

In the steady state, the voltage over the inductor increases as a result of Faraday's law.

What is steady state error in control system?

Steady state error in control systems is the difference between the desired output of a system and the actual output when the system reaches a constant state under a specific input. It indicates how well the system is tracking the desired setpoint. Lower steady state error values indicate better performance of the control system.


What are the differences between steady state and rapid equilibrium in a system?

In a system, steady state refers to a condition where the system's variables remain constant over time, while rapid equilibrium occurs when the system quickly reaches a balance between different components. Steady state involves a stable state of the system, while rapid equilibrium involves a quick adjustment to reach a balanced state.


What are the characteristics of a system that is overdamped?

An overdamped system is characterized by slow response time and no oscillations in its output. It reaches its steady state without any overshoot or oscillations.


Why don't capacitor discharge completely in an RC circuit?

Capacitors do not get "full" like a glass of water. The current into a capacitor is the rate of change of charge, so it's equal to C * dV/dt or something. If the voltage is constant, there's no current. If the voltage on both sides of the resistor is the same, there's no current through the resistor and hence into the capacitor, so that's the steady-state - what you call "full" - the capacitor charged to the supply voltage.


How is the process of calculating steady state in a system typically approached?

The process of calculating steady state in a system is typically approached by analyzing the system's inputs, outputs, and internal dynamics to determine when the system reaches a stable equilibrium. This involves studying the system's behavior over time and identifying any factors that may cause fluctuations or disturbances. By understanding these factors, engineers can predict and control the system's steady state behavior.
