Calculating current across capacitor by adding the transient voltage and steady state voltage 

 Calculating unit step of Parallel RLC circuit  :

RLC circuit Response Lab

Pre Lab : 

using nodal analysis we are trying to calculate the voltage across the resistor across resistor R2

We calculated our alpha,  natural frequency, and damping frequency  of the circuit, according to our calculation the current response across the resistor is an underdamped reaction .
We build our board  :

Then we scope the voltage across the 1-ohm capacitor we obtain a curve that looks slightly underdamped or close to critically damped oscillation instead.

Summary 

To calculate a current or voltage across RLC circuit we can add the transient response and steady state voltage. In our Lab, we obtain a result that is totally off from our expectation, We suspect this result might result from circuit, to be sure we will redo this experiment when we have an extra time.
