Wait-Will too much amperage hurt a device? (Explained)

The circuit inside the phone controls the number of amps entering the battery. So, if the voltage is correct, ... The only way amperage can damage the electronics is if the voltage is high, which can cause the …

When current flows from a battery, does voltage decrease?

The voltage of the battery depends on the chemistry of the cell it is based on. For ex, a Lithium-Polymer cell has a nominal voltage of 3.7V and that of a lead-acid cell is 2V. For cells belonging to a particular chemistry, the voltage depends on many factors, the prominent one being the concentrations of the electrolyte, electrodes etc.

18.5 Capacitors and Dielectrics

The battery is initially at zero volts, so no charge is on the capacitor. Slide the battery slider up and down to change the battery voltage, and observe the charges that accumulate on the plates. Display the capacitance, top-plate charge, and stored energy as you vary the battery voltage.

How much voltage/current is "dangerous"?

A 9 V battery on the tongue almost certainly won''t kill. A 9 V battery across the chest with saline solution (or sweat) just might - probably not. A 12 V "car battery" or any high current source from a few volts up MAY kill in the very worst case. Hand to hand, I have never heard of shock occurring or being felt.

What happens if an LED is connected to a supply voltage greater …

In reality the battery voltage will drop a bit because it will be cranking out a lot of current (batteries have internal resistance which varies with charge state, discharge history, temperature and other factors- maybe a few ohms for a fresh 9V battery), and the LED voltage will increase (LEDs increase voltage with current in a nonlinear way ...

What would happen if I connect a battery which has lower voltage …

You can safely use it to charge a Lithium-ion battery provided that you have mechanisms in place to handle fault conditions such as an over-discharged battery (must be charged at a lower current until reaching 3.0V/cell), charger malfunction (not limiting current or voltage), cell voltage imbalance, and excessively high battery temperature.

Safe Handling of High Voltage Battery Systems

With any high voltage battery, there is always a risk of creating an electrical arc anytime time the ignition is turned on or off. Electrical arcs are by no means universally an HV battery problem. Any electrical switch can result in an electrical arc whenever a circuit is closed. The manner in which these harmful arcs are mitigated in HV ...

charger

So, to answer your question, Yes, 15 volts is too high. Most car alternators, that normally recharge your battery after every start, and provide power while the engine is running, are normally voltage regulated to about 13.8 to 14.0 volts. Up to this voltage and at normal temperatures, the battery will only gas very slightly.

Laptop battery: is voltage really important to respect?

My stock battery was a 6-cell 4000mah 11.1v and the new battery is an 8-cell 4800mah 14.8v. I know that 8-cell and 4800mah is okay, but what about the 14.8v instead of 11.1v? The battery description says it''s compatible with my laptop model (AS5100, model BL51), but the voltage difference makes me wonder. Will the laptop only take what it needs?

Alternator''s extra electricity

The voltage will drop when this happens, because the battery will only discharge if the voltage drops to less than it''s static state, which is around 12.5V for a healthy battery. ... "bottle generators" on bicycles are PMAs, and they would blow out the headlights at high speeds–the "voltage regulator" principle employed there is to ...

Using a higher Amps charger than original: Bad? (Explained)

The only way it can damage the battery is if an incorrect voltage is used, i.e., a higher voltage than the device is rated to accept. This can result in a high amount of amps drawn into the battery and damage it. This is why it''s critical to use the correct voltage. Benefit. Now you might wonder if it is fine to use a higher amperage charger.

How a battery works

The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device for.

Can I use batteries of higher amperage?

Further, the product of the battery''s voltage and the electric charge rating is the amount of energy the fully charged battery can (ideally) supply. In short, using batteries with extra energy capacity will not harm your device, but would, instead, power the device for a longer time (all other considerations unchanged).

electricity

If you are comparing two voltages with identical currents, you cannot be talking about the same bulb in both cases. This means that you are comparing two different bulbs, and there is no way to tell which will be brighter, since different bulbs can be designed for different luminous efficacy, which is light per unit power.

Understanding Solar Panel Voltage for Better Output

It''s the voltage when no power flows. You''ll find that VOC typically falls between 21.7V to 43.2V. When you shop for solar panels, this is an important spec to compare. Voltage at Maximum Power (VMP or …

What voltage is a car battery? — explained

If, after starting, the voltage lies between 12.8 to 13.2 volts, the alternator may not be able to charge the battery. The average voltage a car battery is supposed to have after starting should lie between 13.2 to 14.8 volts. A voltage above 14.8V when the engine is running is too high and may damage the battery.

Is it really OK to supply more current than what the component is …

The key thing here is if the supply survives and the voltage has dropped, then there is less voltage across the resistor which means there will be less current required to satisfy Ohms law - now this all happens in a very quick transient, so essentially all you see is a 5Ohm resistor with a very low voltage across it.

How dangerous are high voltage batteries in water?

The current will find its lowest impedance path. If that happens to be your body (a good possibility, considering salt water) then it could pose a hazard. As a reference, body salinity is about 0.4%. Seawater is about 3.5%. So saltwater is a much better conductor than the human body. One thought would be to have a grounding area …
