Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The direction of induced current is always such as to oppose the change that causes it.
Reason (R) : The direction of induced current is given by Lenz's law.
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
- Assertion (A) states that the direction of induced current always opposes the change that causes it. This is a direct statement of Lenz's Law, which is a fundamental principle of electromagnetic induction. So, Assertion (A) is true.
- Reason (R) states that the direction of induced current is given by Lenz's law. This is also a true statement, as Lenz's Law explicitly defines the direction of induced current in a way that aligns with the principle of energy conservation (by opposing the change).
- Furthermore, Reason (R) directly explains why Assertion (A) is true. Lenz's law dictates the opposing nature of the induced current.
Therefore, both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
