History of Wheatstone bridge

Difference (from prior major revision) (no other diffs)

Changed: 7c7

Detecting zero current can be done to extremely high accuracy. If R1, R2 and R3 are known to high precision, then Rx can be measured to high precision. Very small changes in Rx disrupt the balance and are readily detected.
