I'm expecting a midterm question about the circuit below that involves the equation t=RC and using a Laplace transform. We won't actually be using differential equations. Memorizing a certain equation is all we need, but we're not told what it is. I've found a lot of equations when looking up Laplace transforms. Which equations would be helpful for analyzing this circuit, and where in the circuit could they be applied?

Using the Laplace transform in circuit analysis works just like normal complex analysis. You just plug \$s\$ instead of \$j\omega\$ everywhere.
The interesting part comes after you calculate one thing or another since you can use Laplace transfer function to draw a Bode (frequency and phase response) plot or to calculate the circuit's response to any stimulus.
