1. The problem statement, all variables and given/known data I've been reading about transistors now for a while and there is something that doesn't add up. It's about how the collector in a transistor amplifies the output voltage. And then they say... [QUOTE="williamson-labs.com]When operating with a collector resistor (RL): the output voltage from the collector is an amplified voltage.[/QUOTE] What I was thinking is that when the collector current increases (amplification is usually around 100) the voltage is amplified, hence a high output at the collector. But high current at the collector would mean a big voltage drop in it's resistance and hence low output voltage in the collector. So my question is basicly...is it low current or high current in the collector that amplifies the voltage there?
