an electric circuit.
NCERT Class VIII
Science - Exemplar Problems
Chapter 14. Chemical Effects of Electric Current

Answer 1

Its Heating Effect
The heat generated by electricity heats up the filament of tungsten and the heat is converted into light

Answer 2

The factors that affect the production of heat in a wire through which an electric current flows are the length and thickness of the wire, the duration of flow of current, and the material of the wire.When an electric current flows through a wire, the wire gets hot.An electric bulb also works on the heating effect of electric current. The filament of an electric bulb gets heated to such a high temperature that it starts glowing.
