In a series LCR circuit at resonance, which of the following is maximum?

What is the unit of resonant frequency?

The resonance frequency of the tank circuit of an oscillator when $L = \frac{{10}}{{{\pi ^2}}}mH$ and $C = 0.04\mu {\rm{ }}F$ are connected in parallel is

At resonance in an LC circuit, the impedance is:

In a series resonant R-L-C circuit, the voltage across R is 100 V and the value of $= 1000\;{\rm{\Omega }}$ . The capacitance of the capacitor is $2 imes {10^{ - 6}}\;{\rm{F}};$ angular frequency of AC is $200{\rm{\;rad\;}}{{\rm{s}}^{ - 1}}$. Then the potential difference across the inductance coil is

A circuit has a resistance of 11Ω, an inductive reactance of 25Ω and a capacitative resistance of 18Ω. It is connected to an ac source of 260V and 50Hz. The current through the circuit (in amperes) is

For a series L – C – R circuit, the phase difference between current and voltage at the condition of resonance will be

An LC circuit has a natural frequency of 50 kHz. If the capacitance is doubled and the inductance is halved, the new resonant frequency will be:

An LC circuit has an inductance of 0.2 H and a capacitance of $2 imes 10^{-6}$ F. What is the resonant frequency of the circuit?

The resonant frequency of an LC circuit is doubled when the capacitance is changed to:

A 10 ohm resistance, 5 mH coil and 10 μF capacitor are joined in series. When a suitable frequency alternating current source is joined to this combination, the circuit resonates. If the resistance is halved, the resonance frequency
