I hate working.
There are much better things to do.
Nailed it! I’ll add “between any two selected points” for Voltage, Current, and/or Wattage. Can you call a variable pot on a guitar amp “gain” then distort the signal later.. apparently that’s how it went down. ;-)Very good, I think I'm going to like this place. . The simple answer to "What is gain?" could be, simply put, "the ratio between input and output. A gain of 1, also known as unity gain, is when input voltage is equal to output voltage. A gain of 2 is a 1:2 ratio, and so on.
