Absolute Pressure vs Gauge Pressure - Fluid Mechanics - Physics Problems
This physics video tutorial provides a basic introduction into absolute pressure and gauge pressure. The gauge pressure is the difference between the absolute pressure and the atmospheric pressure. A positive gauge pressure means the absolute pressure is above the atmospheric pressure.

EEVblog #732 - PCB Sheet Resistance
Fundamentals Friday What is Sheet Resistance? Did you know that the resistance of a square copper PCB trace is the same regardless of the size? Dave explains the theory behind this rather counter-intuitive concept called Sheet Resistance, and demonstrates that it is in fact true. What is
