Newman, Ian A.; Pickard, Barbara G. – BioScience, 1975
Describes the construction and operation of a network of entirely passive electrical components that gives a response to an electrical shock similar to an action potential. The network of resistors, capacitors, and diodes was developed to produce responses that would mimic those observed, for example, when a dark-grown pea epicotyl is shocked…

Friesen, David; Chalmers, Hal – Educational Leadership, 1973
Author proposes that the traditional concept of the teacher as a servant of the community may act as a resistor to change and may have to be overcome before any significant change in the status of teachers can occur. (Author/RK)

King, John G.; French, A. P. – Physics Teacher, 1995
Presents several resistance measurement experiments based on the function of a magnetic multimeter. Resistance is measured in terms of the current that the internal dry cell drives through the unknown resistor connected across the input terminals. For use with digital and nondigital multimeters. (LZ)

Kolodiy, George Oleh – Journal of Computers in Mathematics and Science Teaching, 1991
Described is a LOGO computer program that enables students to investigate the relationship between a digital number and the resistance in a variable resistor used to generate that number. Likewise, actual temperature readings and the corresponding resistance within a thermistor can be used for data gathering and subsequent analysis. (JJK)
