Give the value of impedance in resonance condition.

What is resonance?

A sine voltage having maximum value of 283 V & frequency of 50 Hz is applied to LCR series connection where R=3 Omega , L = 25.48 mH & C=796 mu F. Then impedence is ________ at resonance condition.

In an A.C. circuit, resistance = 12 Omega and capacitance reactance = 9 Omega are connected in series, then the value of impedance of a circuit will be ..........

Suppose the frequency of the source in the previous example can be varied. (a) What is the frequency of the source at which resonance occurs? (b) Calculate the impedance, the current, and the power dissipated at the resonant condition.

Give value of speed of light in free space.

While measuring the speed of sound by performing a resonance column experiment, a student gets the first resonance condition at a column length of 18 cm during winter. Repeating the same experiment during summer, she measures the column length to be x cm for the second resonance. Then

Give a suitable example of multinucleate condition (syncytium) in which karyokinesis is not followed by cytokinesis?
