Answer #1

(A) TRUE. Capacitors can be charged by AC as well as DC sources.

(B) FALSE. Unlike a resistor capacitor does not dissipate energy.

Capacitors are devices that store charge, so Instead it stores energy in the form of electrostatic field lines between its plates.

(C) FALSE. Capacitors are made of two conductive plates which are not connected to each other but are electrically separated by either air or some other good INSULATING material known as Dielectric.

(D) TRUE. If one plate of a capacitor has a charge of +Q, then the other plate must have a charge of -Q due to induction( positive charge always induces negative charge)
