Alternating Cur...

If in a series L-C-R ac circuit, the voltages across R, L, C are $$V_{1},V_{2},V_{3}$$ respectively. Then the voltage of applied AC source is always equal to :

An inductance and resistance are connected in series with an A.C circuit. In this circuit

If a capacitor is connected to two different A.C. generators, then the value of capacitive reactance is:

A capacitor is connected to an A.C. circuit, then the phase difference between current and the voltage is :

Ratio of impedance to capacitive reactance has

Statement ( A ) : The reactance offered by an inductance in A.C. circuit decreases with the increase of AC frequency.
Statement ( B ) : The reactance offered by a capacitor in AC circuit increases with the increase of AC frequency.

A mixer of 100$$\Omega $$ resistance is connected to an A.C. source of 200V and 50 cycles/sec. The value of average potential difference across the mixer will be:

Choose the wrong statement of the following :

The equation of an alternating voltage is E=220E=220 .Then the impedance of the circuit is:

An inductor has a resistance $$R$$ and inductance $$L$$. It is connected to an AC source of emf $$E_{v}$$ and angular frequency $$\omega$$; then the current $$I_{v}$$ in the circuit is :
