What is resonance ? What is resonant frequency ?

A 100 mH inductor, a 20 muF capacitor and a 10 ohm resistor are connected in series to a 100 V, 50 Hz a.c. source. Calculate : (i) Inpendance of the circuit at resonance (ii) Current at resonance (iii) Resonant frequency.

An ac generator G with an adjustable frequency of oscillation is used in the circuit, as shown. To increase resonant frequency of the circuit, some of the changes in the circuit are carried out. Which changes would certainly result in the increase in resonant frequency ?

For the series LCR circuit shown in the figure, what is the resonance frequency and the amplitude of the current at the resonating frequency

In the given figure, which voltmeter will read zero voltage at resonant frequency?

An open pipe is in resonance in 2nd harmonic with frequency f_(1) . Now one end of the tube is closed and frequency is increased to f_(2) such that the resonance again ocuurs in nth harmonic. Choose the correct option

A 10 ohm resistance, 5 mH coil and 10mu F 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

The frequency of a stetched unifrom wire under tension is in resonance with the fundamental frequency of closed tube. If the tension in the wire is increased by 8 N, it is in resonance with the first overtone of the closed tube. The initial tension in the wire is
