Short Answer Type Extra Questions
(1) Why should not directly join two terminals of a cell ?
Solution:
If we join 2 terminals of a cell, current will flow into circuit continuously and go waste. Yhe cell will soon get discharged.
(2) Why should one experiment with socket and wires?
Solution:
Sockets and wires carry a large amount of current. Experimenting with them can be dangerous as might get an electric shock.
(3) Why are the electric wires made out of copper or aluminium though silver is a better conductor of electricity?
Solution:
Al metals are good conductors. Silver is an expensive metal so it is not used make wires of silver, copper and aluminium are used as they are cheaper.
(4) Why electric wires are covered with plastic ?
Solution:
Plastic is a good insulator. Wires are covered with plastic so we don’t get an electric shock.
(5) From the list materials/ objects given below classify as conductors or insulators:
Rubber, cork, pencil lead. Iron nails, wood, safety pins, knitting needles.
Solution:
Conductors – Pencil lead, iron nails, safety pins, Knotting needle. Insulators – rubber, cork, wood.
