If the phase difference between Alternating Voltage and Alternating Current is $$\frac{\pi }{6}$$ and the resistance in the circuit is $$\sqrt{300}\Omega $$ , then the impedance of the circuit will be

The inductance of a resistanceless coil is 0.5 henry. In the coil, the value of alternating current is 0.2 A, whose frequency is 50 Hz. The reactance of circuit is

The capacitive reactance at 1600Hz is 81 $$\Omega $$ .When the frequency is doubled then the capacitive reactance will be:

In an LCR circuit, current is I $$=$$ 10sin100$$\pi$$ t from an A.C. source. The value of average voltage at the ends of the resistance R $$=$$ 10$$\Omega $$ will be

In an A.C. circuit the potential difference across an inductance and resistance joined in series are respectively 16V and 20V. The total potential difference across the circuit is

A coil is used in a circuit in which an A.C. of frequency 50Hz is flowing. The self-inductance of the coil, in order to produce an impedance of 100 $$\Omega $$ , will be ___ H

In an LCR series circuit, the rms voltages across R, L and C are found to be 10 V, 10 V and 20 V respectively. The rms voltage across the entire combination is

The source frequency for which a $$5 \mu$$ F capacitor has a reactance of 1000$$\Omega $$ is

The inductive reactance of a coil is 2500 $$\Omega $$ . On increasing it’s self-inductance to three times, the new inductive reactance will be:
