Heating and Luminous Effects.—When a current is passedthrough a eoiuluclor its is raised, and ifllie resistance be great enough it may l)ecoine luminous,or even fused. An example is seen in the common incan-descent lamp in which a narrow filament of carbon israised to incandescence by the passage of the current. Chemical Effects.—The electric current is capable ofcausing a variety of chemical changes, both of combina-tion and of decomposition. For example, if th
