(1/3) > >>

EEVblog:
How to solve the resistor cube problem using equipotential nodes, short and open techniques, and circuit simplification.

0:36 "they happen to be 10K here, point 0, 5%"

are they not 33R, 1%?

This exercise got me looking for the Weathstone bridge, but the more I look at it the more I cannot find any use for it nowdays.

Any op-amp circuit like a non inverter would do a better job...

As I see it the Weathstone bridge is just a good exercise for beginners to learn the Kirchhoff law

Kleinstein:
The Weathstone bridge circuit is still relevant for resistive sensors like strain gages and sometimes still used with PT100 and the like. The highest resolution resistance measurements still used a bridge.

hulk69:
I lookup "strain gages" and it seems that the gage itself is a bridge
