Whats the difference b/n a capacitor & a battery though both can store charge (if i'm not worng) ?

Answer 1

Yes, both do store energy, the main difference being that a cap stores it electrostatically whereas a battery stores it chemically. Due to this difference, batteries are capable of storing far more energy than capacitors per volume or weight, on the order of a factor of roughly about 1000.

Answer 2

you're right about the storage of the charge. It's been a while since I took physics but, I think the difference if that a battery is a continual power source where as a capacitor needs to charge up and once it can no longer hold any more charge it releases the energy and then starts to recharge. So you get pulses or energy.

Answer 3

Capacitors don't store charge for very long in human terms (like only a few seconds max for most), so it is probably not a good idea to call them a "storage device".

A capacitor is two conductors separated by an insulator. Energy is stored in the electric field in-between the plates.

A battery is a chemical generator. Chemicals eat away at a conductor (usually a metal), stripping it of electrons, and thus creating a separation of charge as free electrons move from one side of the battery to the other as a result of chemical reactions.

Answer 4

By appling Voltage to a Capacitor, or a rechargeable battery, you can store Energy, but the difference is that they do not treat as the same when we want to use the energy or whether they are losing their energy. the battery supplies a constant direct to the circuit, but the Capacitor, discharges in respect to the equation q=q(0)(exp(-t/RC)) and the current of I=-(q(0)/RC)exp(-t/RC).so as you see how the exponential function affects this.good luck.

Answer 5

A battery doesn't store charge exactly--it stores chemical energy that can be used to create a charge separation. A capacitor actually stores charge when a voltage is applied to it (battery doesn't need an applied voltage).
