A capacitor, an inductor and an electric bulb are connected in series to an AC supply of variable frequency. If the frequency of the supply is increased gradually, what will happen to brightness of bulb.

An electric bulb and a capacitor are connected in series to a source of an alternating current. If the frequency of the current source is increased then the bulb gives more intense light.

An electric bulb and a capacitor ae connected in an AC source. On increasing the frequency of the brightness of the bulb:

An inductor, a resistor and a capacitor are joined in series with an AC source. As the frequency of the source is slightly increased from a very low value, the reactance

A bulb and a capacitor are connected in series to an a.c. source of varialbe frequency. How will the brightness of the bulb change on increasing the frequency of a.c. source ?

A bulb and a capacitor are connected in series to an a.c. source of variable frequency. How will the brightness of the bulb change on increasing the frequency of the a.c. source. Give reason.

An air core coil and an electric bulb are connected in series with an AC source. If an iron rod is put in the coil, then the intensity of light of the bulb will

A 100Omega resistance, a 0.1 muF capacitor and an inductor are connected in series across a 250 V supply at variable frequency. Calculate the value of inductance of inductor at which resonance will occur. Given the resonant frequency is 60 Hz.
