1.	Statement-I: when a circuit having large inductance is switched off, sparking occurs at the switch. Statement-II: Emf induced in an inductor is given by \(\|e\|=L\left\|\frac{di}{dt}\right\|\)(A) Statement-I is true, statement-II is true and statement-II is correct explanation for statement-I. (B) Statement-I is true, statement-II is true and statementII is not the correct explanation for statement-I. (C) Statement-I is true, statement-II is false. (D) Statement-I is false, statement-II is true.
Answer» Correct option is (A) Statement-I is true, statement-II is true and statement-II is correct explanation for statement-I. When circuit is suddenly switched off, there will be a change in current, and it will lead to induced EMF. \(\|E\| = L \left\|\frac{di}{dt}\right\|\) Now for large ‘L’, E is also high.

Statement-I: when a circuit having large inductance is switched off, sparking occurs at the switch. Statement-II: Emf induced in an inductor is given by \(|e|=L\left|\frac{di}{dt}\right|\)(A) Statement-I is true, statement-II is true and statement-II is correct explanation for statement-I. (B) Statement-I is true, statement-II is true and statementII is not the correct explanation for statement-I. (C) Statement-I is true, statement-II is false. (D) Statement-I is false, statement-II is true.

Answer»

Correct option is (A) Statement-I is true, statement-II is true and statement-II is correct explanation for statement-I.

When circuit is suddenly switched off, there will be a change in current, and it will lead to induced EMF.

\(|E| = L \left|\frac{di}{dt}\right|\)

Now for large ‘L’, E is also high.
