Assertion and Reason Questions on Class 12 Physics Chapter 3 Current Electricity

Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.

Q.1. Assertion : In a simple battery circuit, the point of the lowest potential is positive terminal of the battery.
Reason : The current flows towards the point of the higher potential, as it does in such a circuit from the negative to the positive terminal.

Answer d

Q.2. Assertion : A larger dry cell has higher emf.
Reason : The emf of a dry cell is proportional to its size.

Answer d

Q.3. Assertion : A current continues to flow in superconducting coil even after switch is off.
Reason : Superconducting coils show Meissner effect.

Answer b

Q.4. Assertion : Voltmeter is connected in parallel with the circuit.
Reason : Resistance of a voltmeter is very large.

Answer b

Q.5. Assertion : Ohm’s law is applicable for all conducting elements.
Reason : Ohm’s law is a fundamental law.

Answer c

Q.6. Assertion : An electric bulb becomes dim, when the electric heater in parallel circuit is switched on.
Reason : Dimness decreases after sometime.
