Kirchhoff's Rules
Kirchhoff's Rules
Here's a great example video of how to use Kirchhoff's loop and junction rule. In general here are the equations:
Around a single loop: ΔV = 0
At a junction : Iin = Σ Iout

Under pressure?
Under pressure?
Watch this video to relieve some of that stress and learn more about "Absolute & Gauge Pressure"! This is a topic you should be seeing if you are in PHYS 2a or 4a. If you are confused about any other topic, we highly recommend Organic Chemistry Tutor on YouTube as a resource.
1st Law of Thermodynamics
1st Law of Thermodynamics
The First Law of Thermodynamics is crucial to understand since it allows for the calculation of various parameters such as work and energy. For those with chemistry under there belt, you may notice a slight difference in how the equation is set up. The attached video provides an explanation of the law and why the equation varies from a "chemistry" and "physics" perspective.
