Practice questions

Q1Which pair best classifies the materials in a simple circuit and magnet activity?

A Plastic scale: conductor; iron nail: non-magnetic material
B Rubber band: conductor; aluminium foil: insulator
C Iron nail: magnetic material; plastic scale: insulator
D Wooden stick: magnetic material; steel clip: insulator
Explanation

Iron is a magnetic material because magnets attract it, and plastic is usually an insulator in a simple circuit. Shiny or solid appearance alone is not enough; rubber and dry wood are not conductors in the usual classroom test.

Q2Which teacher instruction is safest for Devika's circuit activity?

A Touch a switchboard wire briefly to test current
B Use a household socket if the bulb is small
C Use only dry cells or batteries, not home sockets or open chargers
D Remove insulation from all wires completely
Explanation

Safety is a concept, not a side note. NCERT not to perform experiments with home or school power supply; Devika's activity should use only cells or batteries under teacher supervision.

Q3Karan breaks a bar magnet into two pieces. Which statement should the teacher accept?

A One piece has only north pole and the other has only south pole
B Each smaller piece has both north and south poles
C Both pieces lose all magnetic property immediately
D The poles change into positive and negative terminals
Explanation

This hard-looking item is actually a clean fact from the magnet chapter. Joseph should reject the tempting cell-terminal language and remember that magnet poles stay paired after breaking a magnet.

Q4A teacher asks students to test four objects by placing each object in the gap of a simple cell-lamp circuit. Which object is most likely to complete the circuit because it is a conductor?

A Plastic scale
B Rubber band
C Metal spoon
D Dry wooden stick
Explanation

A conductor allows electric current to flow easily, so a metal spoon is likely to make the lamp glow when placed in the gap. Plastic, rubber and dry wood are treated as insulators in this basic activity, so their shape does not make them conduct well.

Q5Which statement about an electric cell is correct?

A It has two positive terminals and stores magnetic force.
B It has no terminals and only works as a switch.
C It has positive and negative terminals and supplies electrical energy.
D It attracts iron, nickel and cobalt even when it is not connected.
Explanation

NCERT middle-stage science treats an electric cell as a portable source with one positive and one negative terminal. The other choices mix it up with a switch or a magnet, so they miss the role of the cell in a circuit.

9Meena opens a torch with two cells. Which observation best explains why cell order matters?

ABoth cells must have their positive terminals touching each other
BThe cells work only if placed near a bar magnet
CThe flat metal disc is always the positive terminal
DThe positive terminal of one cell connects to the negative terminal of the next

10Asha says a compass works because its printed dial knows north. Which correction is best?

AThe dial produces electric current in the needle
BThe compass needle is a small magnet that indicates north-south direction
CThe plastic box attracts Earth's iron
DThe switch inside the compass closes a circuit

11In a simple circuit with a cell, wires and a bulb, what is the actual role of a switch?

AIt produces electrical energy for the circuit.
BIt changes an insulator into a conductor.
CIt completes or breaks the circuit path.
DIt makes the bulb magnetic so that it glows.

12A bar magnet is broken into two pieces. At school level, which statement is correct about the poles of the pieces?

AOne piece gets only a north pole and the other gets only a south pole.
BBoth pieces lose all magnetic poles immediately.
CEach piece has both north and south poles.
DEach piece has two north poles and no south pole.

13Imran connects a cell, lamp and wires, but one wire end is loose. Why does the lamp not glow?

AThe circuit path is incomplete, so current cannot flow through the lamp
BThe switch has become the source of current
CThe cell has no positive and negative terminals
DThe lamp glows only near a magnet

14Which pair is correctly matched?

AMagnet - attracts iron
BElectric cell - attracts magnetic materials
CMagnetic material - breaks an electric circuit
DSwitch - supplies electrical energy

15A torch has a cell, a small lamp and a switch. The lamp glows only when the switch is in one position. What does the switch do in that glowing position?

AIt supplies electrical energy to the circuit.
BIt completes the path so current can flow.
CIt changes the two terminals of the cell into one terminal.
DIt turns the lamp wire into a magnetic material.
