Wheatstone Bridge Experiments Based on Digital Voltmeter
Feng Gao · Journal of Xinxiang University · 2011
In the Wheatstone bridge experiment,large inner resistance voltmeter can be used instead of the galvanometer,and the Wheatstone bridge delicacy will be independent of the value of arm resistance.We can reduce the measuring errors and operation steps by using large resistance and high precision resistance panes in the resistance box.
