  1. \(X=\left[\frac{P}{Q} S+\frac{q \Delta r}{p+q+r}\right]\)
  2. \(X=\left[\frac{P}{Q} S-\frac{q \Delta r}{p+q+r}\right]\)
  3. \(X=\left[\frac{P}{Q} S+\frac{q}{p+q-r}\right]\)
  4. \(X=\left[\frac{P}{Q} S-\frac{q}{p+q+r}\right]\)

केल्विन का द्वि-सेतु

F1 S.B 30.5.20 Pallavi D5

केल्विन का द्वि-सेतु व्हीटस्टोन सेतु का एक संशोधित संस्करण है, जिसका उपयोग उच्च परिशुद्धता के साथ कम प्रतिरोध मानों को मापने के लिए किया जाता है।

केल्विन के द्वि-सेतु में, अज्ञात प्रतिरोध दिया गया है:

X = \(\rm\left[\frac{P}{Q} S+\frac{q r\left[\frac{P}{Q}−\frac{p}{q}\right]}{p+q+r}\right]\)

\(X=\left[\frac{P}{Q} S+\frac{q \Delta r}{p+q+r}\right]\)
