Explanation: No, the capacitor cannot be fully charged using alternating current because as soon as the capacitor charges, the alternating current reverses its polarity thereby discharging it.

Explanation: Resistance offered to alternating current by inductor or capacitor is known as reactance which is equivalent to resistance of resistor.

Explanation: The combination of resistance and reactance is known as impedance. It is equivalent resistance of an RLC alternating circuit.

Where Z is impedance, R is resistance and X is reactance.

Explanation: The combination of resistance and reactance is known as impedance. Z=R+jX where Z is impedance, R is resistance and X is reactance. R is real part of Z.

Explanation: The combination of resistance and reactance is known as impedance. Z=R+jX where Z is impedance, R is resistance and X is reactance. X is imaginary part of Z.

Explanation: Only direct current can be stored in the capacitor. Capacitor cannot be fully charged using alternating current because as soon as the capacitor charges, alternating current reverses its polarity thereby discharging it. So, we cannot store ac current in capacitor.
