Battery Capacity
Since the capacity of a battery does not have a unique value, the manufacturers write an approximate value on their products. The approximate value is called Nominal Capacity and does not mean that it is the exact capacity of the cell. Fig. 2.2 shows a typical lithium battery used for cell phones. As it is indicated on the cover of the cell, it has Q n = 3500 mAh …
Using a higher Amps charger than original: Bad? (Explained)
The mobile batteries have a controller built-in that ensures the same input to the battery regardless of whether or not the charger''s current rating is greater than needed. You should choose a charger with a rating of the same voltage, not less nor higher, and a current rating of the same or high to ensure a cooling charging process.

What does battery charger''s current rating mean? [duplicate]
A battery charger limits current going into the battery, and its current rating will be matched to the battery it was designed to charge. Depending on the battery chemistry, voltage may also be limited, eg. Lithium Polymer is 4.2V/cell. However the label usually shows the nominal voltage, eg. 3.7V for a 1 cell Lipo, 7.2V for a 6 cell Nicad.

Fundamental Characteristics of Circuit Breaker
That value must be greater than the maximum load current IB, but less than the maximum current permitted in the circuit Iz. The thermal-trip relays are generally adjustable from 0.7 to 1.0 times In, but when electronic devices are used for this duty, the adjustment range is greater; typically 0.4 to 1 times In.
What happens when a device draws more current than the power …
$begingroup$ A load circuit might, very briefly, draw more than the power supply can output when the load is first turned on. For instance if the load has a lot of capacitors that need to charge up, the charging current might flow in a large spike, which then settles down to much less than the supply''s capacity once the capacitors are charged.

Battery Internal Resistance: A Comprehensive Guide
When a load, such as a motor or a light bulb, is connected to a battery, it draws current. This current flow, combined with the battery''s internal resistance, causes a voltage drop. The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a AA cell.

What happens if an LED is connected to a supply voltage greater than ...
A low current will have it burn dimly, and the rated current will have it burn brightly. Too much current will blow the LED. You limit the current to your desired value (often 15 to 20mA) by putting the correct resistance into the circuit. Use Ohm''s law to work that out. R (ohms) = V (volts) / I (amps).
