/* [[Resistor]] */
The following lines were added (+) and removed (-):
*Rheostat:Two terminal variable resistor used to control current. Although definitions vary, in simplistic terms a potentiometer and a rheostat are both synonyms for variable resistor. However, the rheostat is often clarified as being a variable resistor with only two terminals, and designed to handle higher current than a typical three terminal potentiometer. A potentiometer can be connected as a rheostat by leaving one of the terminals unconnected.
