## Homework Statement

Hello, I got to solve the following second order transient circuit. Obviously, what I need to do first is to find if its critically damped, underdamped, or overdamped.

The circuit can be found in the attachment.

## Homework Equations

Depends, weather the circuit is critically damped, underdamped, or overdamped.

## The Attempt at a Solution

So, what I do is to remove the voltage source by a short and the current source by an open circuit, then assume the switch will be opened at t>0, so there will be an open circuit where the switch was. Then try to find if its a series RLC or a parallel RLC, exactly, how can I do that? I need to know if its a series RLC or parallel RLC to determine weather the circuit is critically damped, underdamped, or overdamped.

Any help would be gladly appreciated!
