What is transient response and steady state response in electrical circuit?

Question

This is the 1st topic in engineering science 2, so i hope you all can help me. thank you!

Answer 1

transient= alternating current= AC
electricity from the wall

Steady state= Direct Current= DC
battery power

Answer 2

Transient Response

Answer 3

Basically, anytime you have inductors or capacitors in a circuit you are going to have some type of a transient response.

Think of when you play a video game and need to target a bad guy. You swing your targeting reticle to right really fast and sweep right past the guy, so you sweep back to the left but go just a bit to far so you tap it just a little bit to the right and you're right on target.
Now assuming the guy doesn't move (or shoot and kill you before I explain this--like he always does to me...):
When you are lined up on your shot, that is a steady state response. You have reached your desired outcome (bad guy is targeted) and nothing else is required to stay like that.

The part where you were lining up your shot was the transient response. There are 3 types of transient resoponses, under damped, critically damped, and over damped. In the example I used above you swung around to far (called overshoot) and had to come back; This is an under damped response they are usually fast to react to changes but take extra time to settle into a steady state (the time spent bouncing around the final state is called pinging, or ringing by some)

Now if you were much better at video games than I am, you might have been able to swing to the right and let go at just the right time to line up on target. This is a criticaly damped response, there isn't much to improve on here you get to steady state about as fast as can be done.

If you were to swing really slow so you wouldn't swing past the bad guy, this would be over damped. It doesn'rt result in overshoot, but usually takes the longest time to achieve a steady state response.

In a circuit inductor and capicitors have charging curves based off of exponents of e. When you have these passive devices in a circuit and initiate a change to the circuit (power on, changing a current or voltage, or removing/adding elements to the circuit) it takes time to get to the new final answer. The time and type of transient depends mostly on the elements in the circuit.

A more academic way to put it is that steady state response is when time approaches infintiy and a transient occurs near to, and at, time equals zero.
