Zero input response of capacitor voltage

Zero-input response: the circuit has no applied source after a certain time. It is determined by natural response and the initial condition. Zero-state response: the circuit has no initial stored energy. ( t : time constant) eq t = í (If t<0, then the circuit is unstable.)

What is the zero-input response of a capacitor?

In this situation, y (t) = x (t), where x (t) is the voltage input and y (t) is the voltage output across the capacitor. Now, my intuitive understanding tells me that the zero-input response is zero because no current has been provided yet and the capacitor is uncharged. But what about the zero-state response?

How do you find a constant for a zero input capacitor?

To find the constant A for the zero input response of a series RC circuit, you can use the initial condition at time t = 0. The initial voltage V0 across the capacitor is given. The constant A is simply the initial voltage V0. Using k = –1/RC, you can find the solution to the differential equation for the zero input.

What is the difference between a complete response and a zero input?

The zero input part of the response is the response due to initial conditions alone (with the input set to zero). The zero state part of the response is the response due to the system input alone (with initial conditions set to zero). The complete response is simply the sum of the zero input and zero state solutions.

Does a capacitor have a zero input?

That means that whatever variation of voltage exists, the capacitor will follow exactly, while the current through it will be infinite in value. Make that impossible, since I=V/R, unless you have special cherokee blood. In short, there is no zero-input since there is a voltage source involved, and zero-state means whatever the source has.

What does it mean to have zero input voltage?

Zero input voltage means having no input for all time. The output response is determined by the initial condition V0 (initial capacitor voltage) at time t = 0. The first-order differential equation simplifies to Here, vZI(t) is the capacitor voltage.

How do you find the zero-input and zero-state responses of an RC circuit?

From my understanding, the zero-input and zero-state responses of an RC circuit can be found by solving for the homogenous and particular solution of the ordinary differential equation found using Kirchhoff's current law. But I am confused as to what happens if there is no resistor in the circuit.

Chapter 9 Transient Response

Zero-input response: the circuit has no applied source after a certain time. It is determined by natural response and the initial condition. Zero-state response: the circuit has no initial stored energy. ( t : time constant) eq t = í (If t<0, then the circuit is unstable.)

Transient response of RC and RL circuits

In many applications, these circuits respond to a sudden change in an input: for example, a switch opening or closing, or a digital input switching from low to high.

We call the response of a circuit immediately after a sudden change the transient …
