Product Code : SCL-EELE-14511
Indian Lab Suppliers supplies the Portable Wheatstone Bridge Apparatus (Product ID: 14511) as part of its electronics engineering lab equipment range. It is a portable four-arm Wheatstone bridge for measuring an unknown resistance by the null (balance) method.
Quick Answer
The unknown resistor is connected across colour-coded insulated binding posts, and the bridge, built from wire-wound resistors, is balanced with dial knobs on a graduated scale until the galvanometer reads zero. At balance P/Q = R/X, so the unknown X = R × Q/P. The galvanometer is moving-coil or moving-magnet depending on model, and the bridge runs from a standard DC supply or dry cells. The range is given only as a few ohms to several kilo-ohms, so please confirm the range, galvanometer type and housing (ABS or metal) at quotation.
