Hall effect measurements have been valuable tools for material characterization since Edwin Hall discovered the phenomenon in 1879. Essentially, the Hall effect can be observed when the combination of a magnetic field …

The Hall effect can be observed when the combination of a magnetic field through a sample and a current along the length of the sample create an electrical current perpendicular to both the magnetic field and the current, which in turn …

This application note discusses a variety of electrochemical applications, including voltammetry, low and high resistivity measurements, battery test, potentiometry, electrodeposition, electrical device characterization, and other tests that involve sourcing and measuring current and voltage and measuring capacitance with high accuracy.

Keithley's approach to differential conductance, a four-wire, source current/measure voltage technique, uses the 6220 and 6221 Current Sources and 2182A Nanovoltmeter.  The current sources combine the DC and AC components into one source, with no need to do a secondary measure of the current, because its output is much less dependent on the changing device impedance
