If two inductances are joined in parallel, the equivalent inductance is 2.4 H, and it becomes 10 H, if they are joined in series. Then, the difference between both of them will be

In the following question, a statement of Assertion is given, followed by a corresponding statement of Reason. Mark the correct answer as
(a) if both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
(b) if both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion
(c) if Assertion is true, but Reason is false
(d) if both Assertion and Reason are false
Assertion: In the phenomenon of mutual induction, self-induction of each of the coils persists.
Reason: Self-induction arises when strength of current in one coil changes. In mutual induction, current changes in individual coils.

If 8 Ω resistance and 6 Ω reactance are present in an AC series circuit, what will be the impedance of the circuit?
