Abstract: There are errors with the measurements due to the existence of the internal resistance by the traditional voltaic method to measure resistance. We attempt to replace the voltameter with the electron beam tester and find that the relative error of measured results is small. This is one way to realize the measurement of electricity quantity with the aid of the mechanical quantity.

Key words: resistance, electron beam, electromagnetic deflection
