Spannung Follower Rechner — Formel
## Voltage Follower (Buffer)
### Principle
**V_out = V_in** (gain = 1)
The buffer presents very high input impedance (megohms) and low output impedance (ohms). It prevents a low-impedance load from dragging down a high-impedance source.

Lösungsbeispiel
3.3 V from a 100k source driving a 100 ohm load.
- With buffer: V_out = 3.3 V (no loading)
- Load current = 3.3 / 100 = 33 mA
- Without buffer: V = 3.3 x 100 / (100000 + 100) = 0.0033 V (severe loading)
