(1) Circuit - (c) Path of the electric current A path for an electric current to flow is called an electric circuit. A closed electric circuit is a continuous or unbroken path between the two terminals of the cell, conducting wires and the bulb. (2) Solar cells - (e) Convert solar energy into electricity They are special type of cells that convert energy from the sun into electricity by the photovoltaic effect. They are used in solar water heater, solar lights etc. (3) Pure water - (a) Bad conductor Electricity is a form of energy. The materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, pure water, plastic, wood, and cloth are poor conductors of electricity. (4) The cell - (b) Part of the circuit The cell is a part of the circuit. An electric cell is a device that changes chemical energy into electricity. (5) Human body - (d) Good conductor The human body is a good conductor of electricity. Materials that allow electricity to pass through them easily are called conductors of electricity. Silver is the best conductor of electricity. column I column II (1) Circuit (c) Path of the electric current (2) Solar cells (e) Convert solar energy into electricity (3) Pure water (a) Bad conductor (4) The cell (b) Part of the circuit (5) Human body (d) Good conductor
