Chapter: Electrical Engineering and Instrumentation - Analog and Digital Instruments
Wheat stone bridge and Kelvin’s double bridge
It is suitable for moderate resistance values: 1 ohm to 10 M ohm. Balanced condition, no potential difference across the galvanometer (there is no current through the galvanometer).
