To learn how to operate a Wheatstone bridge
To determine the resistances of different unknown resistors and compare these to their corresponding theoretical resistances
Categories: Electromagnetism Laboratory
The Wheatstone bridge is a type of bridge circuit used to determine the value of an unknown resistor by comparison with known resistors whose resistances can be varied. In the bridge circuit, only one resistance is unknown and the others are known and variable. You will be calculating the unknown values with the known ones, with the guidance of our lan assistant Amy.
