EEVblog 1472 - Resistor Cube Problem SOLVED

(1/3) > >>

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

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.

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