Homework Statement



I think I am turning retarded. For some reason I can't get the right values for a simple voltage division in the s-domain. Find Vout in terms of Vin

Homework Equations


The Attempt at a Solution



So I do H(s) = (1/s) / ((1/s) + 1 ) = 1/(s+1)
Then Inverse Laplace transform it and get Vin*e^(-t). But shouldn't Vout=Vin(1-e^(-t)) ?

So I think I am ending up with the voltage drop across the resistor instead of the capacitor like it should be...

Can you post the whole problem? I'm quite sure you have left something important out. One error I can see right now is, you haven't laplace transformed the pulse signal.

Thanks so much! That's what I was forgetting.
 

Related to Simple RC Circuit Voltage Division Solution

1. Why am I unable to do a simple RC circuit?

There could be a few reasons for this. It could be due to a lack of understanding of the concept or incorrect calculations. It could also be a problem with the components or connections in the circuit.

2. What is the purpose of a simple RC circuit?

A simple RC circuit is used to control the flow of electric current. It can be used as a filter, timer, or oscillator in electronic devices.

3. How do I calculate the time constant in a simple RC circuit?

The time constant in a simple RC circuit is calculated by multiplying the resistance (R) in ohms by the capacitance (C) in farads. The formula is T = R x C.

4. What are the possible sources of error in a simple RC circuit?

The sources of error in a simple RC circuit could include inaccurate measurements of resistance or capacitance, faulty components, or incorrect connections.

5. How can I troubleshoot a simple RC circuit that is not working?

Firstly, check all the components and connections to make sure they are correct and functioning properly. Then, double-check the calculations for the time constant and make sure it matches the expected result. If the circuit still does not work, try using different components or consulting a professional for assistance.
