Q1In a simple circuit, a bulb, a cell and wires are present, but one wire end is not connected. Why does the bulb not glow?
A closed circuit is a complete path, and the bulb glows only when current can pass through that path. A loose wire makes the circuit open; adding a switch or assuming two cells are always needed does not fix the missing connection.
Q2A 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 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.
Q3Karan breaks a bar magnet into two pieces. Which statement should the teacher accept?
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 bar magnet is tied at its middle with a thread and allowed to hang freely. After it stops moving, what should a student observe?
A freely suspended magnet comes to rest along the north-south direction. It does not settle randomly, does not point east-west as the standard observation, and does not lose its paired poles by being hung.
Q5Match List I with List II for a classroom sorting activity.
The correct match keeps categories separate. Meena should not collapse electrical conduction and magnet attraction into one property; the cell supplies energy, the switch controls the path, and iron is a magnetic material.

11In a simple circuit with a cell, wires and a bulb, what is the actual role of a switch?
12A 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?
13Imran connects a cell, lamp and wires, but one wire end is loose. Why does the lamp not glow?
14Which activity plan best fits the REET classroom meaning of electricity and magnetism?
15Assertion: A switch may be placed anywhere in a simple circuit. Reason: A switch either completes or breaks the circuit path.
