These days it can be used for many other purposes other than calculating resistances. It is also called Resistance Bridge because it is heavily dependent on resistors for its functioning. Even though the measurement of resistance these days can be done easily using the multi-meter, Wheatstone bridge can still be used to measure unknown resistances fairly accurately, down to the milli-Ohms range. It was named Wheatstone bridge for his contribution to its development. Samuel Hunter Christie originally invented it in 1833, but Sir Charles Wheatstone later developed it to the form we know today in 1843. It uses the concept of potential balancing using variable resistance. It was also used to calibrate measuring instruments such as voltmeters, ammeters, etc. Wheatstone bridge is an electrical circuit which is used to calculate unknown resistance.
