(3) Electric cell has ___ terminals.
(a) 3
(b) 2
(c) 4
(d) 8
Answer: – b) 2
Explanation: – electric cell has two terminals which is positive terminal and negative terminal.
(4) Which of the following device is used to break the electric circuit?
(a) switch
(b) Electric cell
(c) wire
(d) none of there
Answer: – a) switch

(5) Which of the following statement is correct?
(a) an electric bulb has a filament that is connected to its terminals
(b) Insulators do not allow electric current to pass through them.
(c) Electric cell produce electricity from the chemicals stored inside
(d) all of these
Answer: – d) all of these
Explanation: – all of these statements are correct.
(6) Which pair is wrong among the following?
a)Insulators | Do not allow electric current to pass through them. |
b) conductors | Allow electric current to pass through |
c) Electric cell
|
Has two positive terminal |
d) Electric bulb | Has a filament that is connected to its terminal |
Answer: – c) electric cell – has two positive terminals.
Explanation: – all the pair are right except option ( c ) because electric cell has one positive and one negative terminal ; it does not have two positive terminals.
(7) Which of the following allow the electric current to pass through it?
(a) conductors
(b) insulator
(c) terminal
(d) all of these
Answer: – a) conductors
Explanation: – conductor allows the electric current to pass through it.
Insulator doesn’t tolerate the electric current to go by it.
Terminals are the two end points of the electric cell.
(9) Electric wire is made up of which of the following?
(a) zinc
(b) Aluminum
(c) copper
(d) none of these
Answer: – c) copper
Explanation: – Electric wire is made up of copper.
(10) Which of the following is conductor of electricity?
(a) Human body
(b) water
(c) metal wire
(d) all of the above
Answer: – d) all of the above
Explanation: – all of the above examples water, human body and metal wire are the conductors of electricity.
(11) Metallic electric wire are covered with _____.
(a) Cotton
(b) Rubber
(c) Plastic
(d) None of there
Answer: – c) plastic
Explanation: – metallic electric wires are covered with plastic, because plastic is the insulator. It does not allow passing the electric current through it hence using the plastic over the metal wire will prevent one from getting shocked.
(12) Which of the following is an example of insulator?
(a) plastic
(b) wood
(c) both a and b
(d) metal
Answer: – c) both a and b
Explanation: – both plastic and wood are bad conductor of electricity, electric current do not pass through both of them. While metal is the good conductor of electricity.
(13) Which of the following do not conduct electricity?
(a) paper
(b) Rubber
(c) plastic
(d) all of these
Answer: – all of these
Explanation: – paper, rubber, and plastic are the insulator so it does not conduct electricity.
(14) Battery contain ______ terminal
(a) 3
(b) 2
(c) 4
(d) 6
Answer: – b) 2
Explanation: – battery contains one Positive and one negative terminal.
(15) Negative terminal of an electric cell is _________.
(a) metal cap
(b) metal disc
(c) both a and b
(d) none of these
Answer: – b) metal disc
Explanation: – metal disc is negative terminal while metal cap is positive terminal of electric cell.
(16) Thin wire used in the bulb that gives light is called as__________.
(a) insulator
(b) conductor
(c) filament
(d) terminal
Answer: – c) filament
Explanation: – filament is the metal wire which is attached to two terminals in the bulb, when one on the switch then it gives the light.
(17) Mercury is an example of____________.
(a) terminal
(b) conductor
(c) insulator
(d) none of these
Answer: – conductor
Explanation: – Mercury is a metal and metals are the conductor of electricity.
(18) Which of the following statement is correct?
(a) The bulb glow only when current flow through the circuit
(b) A cell converts electrical energy to chemical energy
(c) Electric current can pass through a copper
(d) All are incorrect
Answer: – b) a cell converts electrical energy to chemical energy.
Explanation: – cell convert electrical energy to chemical energy is incorrect because cell convert chemical energy to electrical energy. While other two sentences are correct.
