Questions:
A capacitor is able to serve as which of the following?
Answer:
By classification a capacitor is a charge storage device. In storing charge a capacitor as well stores energy. If you connect a charged capacitor transversely a resistor the capacitor will discharge through the resistor and the energy that was stored in the capacitor will manifest itself as a temperature increase of the resistor.
The amount of energy stored in a capacitor is able to be expressed in terms of the charge on the capacitor as ½ 1/C Q2 or in terms of the voltage across the capacitor as ½ C V2.
The minimum real charge on any particle which can exist is: (1)1.6x 10 -19 coulomb (2) 1.6x 10 -10 coulomb (3)4.8 x 10 -10 coulomb (4)Zero Ans: (1)1.6x 10 -19 c
