Amplifier Memes

Engineering students facing their electronics exam be like: "I fear no man. But that thing... it scares me." The operational amplifier (op-amp) symbol strikes fear into the hearts of even the bravest students! That little triangle with the plus and minus inputs might look innocent, but when you're trying to calculate gain, impedance, and feedback circuits at 2 AM before your exam... it becomes the final boss of electrical engineering! Even Tesla would be sweating bullets right now.
