# Strain connections

## Single strain

Individual strain consists of two 1k resistors connected as a voltage
divider. Connection with two fixed 1k resistors as a voltage divider
creates a full bridge. **50kg max.**

## Double strain

Using two single strain half bridges together forms a full bridge. **100kg
max.**

## Quadruple strain

Using four single strain half bridges together again forms a full bridge,
with the resistance doubled. **200kg max.**
