At resonance, a circuit exhibits maximum voltage across the load with minimal impedance, leading to maximum current flow. The inductive and capacitive reactances are equal in magnitude but opposite in phase, resulting in their cancellation. This condition enhances the circuit's ability to select specific frequencies, making it highly efficient for applications like tuning and filtering. Additionally, the circuit's bandwidth is at its narrowest, concentrating energy around the resonant frequency.

Why series resonance is called voltage resonance?
Series resonance isn't generally referred to as 'voltage resonance', but the expression probably comes from the fact that, at resonance, the voltage drop across the inductive component of a circuit is exactly equal to the voltage drop across the capacitive component of the circuit and, if the resistance of the resonant circuit is low in comparison with its reactance, then each of these voltage drops can be significantly higher than the supply voltage.
When a parallel LC circuit is tuned to resonance the tank circuit draws?

Why the impedence of rajector circuit is maximum at resonance?
In a RLC circuit, the impedance is maximum at resonance because the inductive and capacitive reactances are equal in magnitude but opposite in phase. This results in their cancellation, leaving only the resistance in the circuit. At this point, the circuit allows maximum current to flow, as the impedance is minimized. Thus, the maximum impedance occurs when the reactances balance each other out, leading to resonance.
What is the power factor on a circuit in resonance?
You are presumably referring to an 'R-L-C' circuit. At resonance, the load current is in phase with the supply voltage and, so, the power factor is unity.
When the circuit is said to be in resonance?
For a particular frequency if the current or the voltage of the circuit is Maximum or Minimum then that circuit is said to be in resonance .

Why a parallel resonant circuit is called as rejecter circuit?
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
Why current is maximum in series resonance circuit?
Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.
When a parallel LC circuit is tuned to resonance the tank circuit draws?

Resonance in an L-C-R AC Series circuit experiment?
In an L-C-R AC series circuit, resonance occurs when the capacitive and inductive reactances cancel each other out, resulting in minimum impedance. This causes the current in the circuit to be at its maximum and the power factor to be unity. By measuring the frequency at which resonance occurs, one can determine the values of the inductor, capacitor, and resistor in the circuit.

When L is doubled and C is halved the resonance frequency of series tuned circuit becomes?
When L is doubled and C is halved in a series tuned circuit, the resonance frequency remains unchanged. This is because the resonance frequency of a series tuned circuit is determined by the formula f = 1 / (2π√(LC)), and doubling L and halving C cancels each other out in this formula, resulting in the same resonance frequency.
