Does anyone know when and why it came to pass that we're seeing V replacing E in electronics math? Seems pointless, but would be interested to know why someone thought it was necessary.

Amplifiers make signals bigger. Amplification is often the most basic operation of an electronic circuit. There are many kinds of amplifier designs. We will describe the operational amplifier, …

Do capacitors store charge? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other …

With a little electronic equipment, you could put together your own logic gates, like this video shows. Here are the homemade circuits for AND and OR gates from that video:

I took a year of calculus in college (calc 1 & 2) as a hard science major about 10 years ago which included differential equations but have not touched them since. Would my professional …
