Assertion: If the frequency of alternating current in an `AC` is circuit consisting of an inductance coil is increased then current gets decreased.
Reason: The current is inversely proportional to frequency of alternating current.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer

A

Explanation

When frequency of alternating current is increased, the effective resistance of the inductive coil increases. Current `(X_(L)=omegaL=2pifL)` in the circuit containing inductor is given by `I=V/(X_(L))=V/(2pifL)`. As inductive resistance of the inductor increases, current in the circuit decreases.
