After a lot of research and experimentation I have come to learn that the sentence "This is a 1.5V, 2800mAh battery" is entirely a lie. (i.e., the potential difference between the terminals of a battery changes over time and the shape of the graph is dependent on battery chemistry, ambient temperature and current draw, as is the useful energy capacity.

So i would like to try to power my webcam from separate power source. (Dual 18650 li-ion batteries in series) I suppose to connect web camera USB power pins to a li-ion accumulators, via LM7805 1A linear regulator. So now you got the idea, and my questions are as follows: Can be "1A" considered suffient current?
How much current can you pull safely off a standard AAA battery?
The maximum current depends very much on the chemistry of the battery. The capacity of the three main (no Lithium) batteries is approximately: Zinc-Carbon: 540mAh; Alkaline: ~1000mAh; NiMH: ~900mAh; The current limit and capacity of any specific battery can be found in its datasheet. For instance, the Duracell MN2400 has the following nice graph:
How does current flow in a circuit with a capacitor?
Displacement current plays an essential role in Maxwell''s equations. Displacement current density is proportional to the time derivative of the change of electric flux density. When electron current flows into one side of a capacitor, the electrons accumulate, as there is no place for them to go.

Batteries, current, and Ohm''s law. 7-10-00 Section 18.1 - 18.4 ... When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction. ...
voltage
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
batteries
$begingroup$ @user1564795 sorry I can''t comment on your post, only mine. Anyway, the amount of current depends on the resistive element you are measuring. Quoting from wikipedia, "To measure resistance, a small battery within the instrument passes a current through the device under test and the meter coil.

I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?

High Current or High Voltage that damages components?
1) For example if you have a working circuit with a 10V battery, fixed 5 Ohms resistance and a current of 2A. If you then swap that battery to 20V, would it be the new current of 4A that does the damage or that fact that the voltage is now 20V? Both values are higher than they should be so which factor will do the damage, both?
How do I determine whether a switch can handle the power/current …
In short, you can pretty much try the switch you have in mind. 5A is not a lot less than 5.5A and the audio signal is rarely full-time full-power. The result may or may not be acceptable for you. Either way, you won''t lose much. At …

power
Given that an inverter might only be 90% efficient, the input power could be as high as 3.333 kW and then the current from a 12 volt battery would be 278 amps. Of course, the inverter may have a surge power rating of 4 kW and then the surge current taken from the 12 volt battery might be as high as 370 amps.
How does the current know how much to flow, before having …
Actually, the current doesn''t know how much to flow at t=0. Every resistor have some capacitance, since they consist of the conducting sides separated with an insulator (even though not perfect). Because of this capacitance, at t=0, current rushes as much as the power supply can supply. Then it slows down after a while to its normal value.

power supply
Supply current drawn for the speakers alone would be: Current [Ampère] = Power [Watt] / Voltage[Volt] I = P / V = 5.6 / 5 = 1.12 A. Accounting for efficiency, you are looking at 1.12 / 0.89 = 1.26A. This is with 8Ω load, efficiency with a 4Ω load will be worse. The datasheet for the amp states another 5.5 mA supply current.
Maximum current draw from 12v sealed lead acid battery?
Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.

$begingroup$ 16.5 volts is a tradeoff between voltage and current and is likely related to the battery voltage so the battery charger will be efficient. Lots of current means resistive losses in the power cable and it requires beefier connectors. The battery is probably a 4 cell lithium polymer, with 4.2 volts per cell resulting in 16.8 ...
