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)
The purpose of a parallel circuit resonance is to magnify voltage. In a parallel resonance circuit, the impedance of the circuit becomes purely resistive at the resonant frequency. This means that the reactive components, such as inductors and capacitors, cancel each other out, resulting in a circuit with minimal impedance.At resonance, the voltage across the circuit is primarily determined by the resistance, and it reaches its maximum value. This phenomenon is exploited in various applications, such as in radio tuning circuits and inductor-capacitor (LC) tank circuits used in electronic devices. Parallel resonance allows for efficient transfer and magnification of voltage at a specific resonant frequency.

B. Impedance of the circuit
C. Applied voltage to the circuit
D. Resistance of the circuit
The inductance of a coil can be increased by
A. Increasing core length
B. Decreasing the number of turns

The parallel Resonance Circuit Magnifies Current while Series Resonance Circuit Magnifies Voltage.
right answer is A
Answer is wrong
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.
A should be correct
A is the correct answer
I think answer is wrong
