The purpose of a parallel circuit resonance is to magnify

A. Current

B. Voltage

C. Power

D. Frequency

Answer: Option B

Solution (By Examveda Team)

In a parallel circuit resonance, the purpose is to magnify voltage.

Resonance in a parallel circuit occurs when the impedance of the circuit becomes purely resistive, causing the current to be magnified and the voltage across the circuit elements to be maximized.

Option A: Current. While resonance does affect current, the primary purpose is to magnify voltage.

Option B: Voltage. This is correct as resonance in a parallel circuit results in the amplification of voltage.

Option C: Power. While resonance can affect power, its primary purpose is not to magnify power but rather voltage.

Option D: Frequency. Resonance does not magnify frequency but occurs at a specific frequency where the impedance of the circuit is minimized.

Therefore, the correct answer is Option B: Voltage.

    As per the above source, magnify current and not voltage.

    Kindly very your statement.

    Kindly email me your justification as well. Thank you

    In parallel circuit current magnify and in series voltage magnify so A is right ansere

    Option A (Current) is right Answer

    in series resonance circuits the Q-factor gives the voltage magnification of the circuit, whereas in a parallel circuit it gives the current magnification.
