In electronics there is hardly anything simpler than a voltage divider circuit. Most people know that Vo = R2 / (R1 + R2) * Vi
, where R2 / (R1 + R2) = f
is the divider fraction. But it is not obvious how to choose the resistor values. You can start with one value, calculate the other one, get...
Usłyszałem dziwny szelest w piwnicy. Patrzę... polna myszka siedzi sobie i ząbkami serek skrobie.
Nazwałem myszkę Jerry. Jak on tam wlazł? Jak by go tu złapać?
