Loading...Hello! Let's assume the output of my function generator has 50 ohms (internal resistance) and I load it with a resistance greater than 50 ohms. Surely the voltage drop across the load will be greater than the set value? If R is less than 50, the voltage drop across the load will be less than…
In the past, you could travel to England with your ID, but what about after Brexit?
Hello, I have a problem with my Audi: when I try to raise the rear right window, it goes down briefly and then goes up. Sometimes it just goes down and then only goes back up again with help. Does anyone know how I can solve this problem without spending hundreds of euros at a…

Uzw.
Thank you.
Yes, that then swings up – and applies primarily to the frequency at which this feedback “best” works (which can also be checked cleanly about the oscillation condition by calculation). That’s why you just hear a whistle at exactly this frequency.
If you call “live” with a radio station, you should also set the radio sound quietly to avoid this feedback.
