Directions : In the following questions, A statement of Assertion (A)...
In electromagnetic induction, magnetic energy, mechanical energy are converted into electrical energy. So, Faraday’s laws of electromagnetic induction are direct consequences of law of conservation of energy. Hence assertion is true. In a L-R circuit, L/R parameter has the dimension of time. Hence the reason is false.

Directions : In the following questions, A statement of Assertion (A)...
Explanation:
Assertion (A):
- Faraday’s laws of electromagnetic induction are consequences of the law of conservation of energy.
- This statement is true because Faraday’s laws of electromagnetic induction state that whenever a magnetic field changes in a closed loop, an emf is induced in the loop. This induced emf is a result of the conservation of energy, where the changing magnetic field produces an electric field and work is done to move charges around the loop.
Reason (R):
- The parameter LR in a L-R circuit has the dimension of time.
- This statement is false because the parameter LR in a L-R circuit does not have the dimension of time. The parameter LR represents the time constant of the circuit, which is the time taken for the current to reach approximately 63.2% of its final value in response to a step input. The time constant is given by the formula τ = L/R, where L is the inductance and R is the resistance.
Therefore, the correct answer is:
- A is true but R is false
