What happens when you keep charging a full battery?
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their highest level.
What happens to the excess electricity?
Excess electricity is surplus electrical energy that must be dumped (or curtailed) because it cannot be used to serve a load or charge batteries. If it cannot be put to use, excess electricity might have to be dissipated in a dump load, which is usually a simple resistive heater or a bank of light bulbs.
What happens when there is too much electricity?
Too much electricity, low demand If too much electricity is fed into the grid in relation to the quantity consumed, the electrical frequency increases. Since power plants are designed to operate within a certain frequency range, there is a risk that they will disconnect from the grid after a period of time. .
What happened to the electrical energy when the phone is being charged?
When the electricity gets into the mobile it is converted and stored as chemical energy inside of the battery and when we use the mobile the previously stored chemical energy is again converted into electrical energy.
Is a charged battery potential energy?
A battery maintains a nearly constant change in electric potential across its terminals. There is energy stored in the battery in the form of chemical potential energy. Yes, it is true that a current can be described as moving electrical charges.
How do you know when a 12-volt battery is fully charged?
A fully-charged 12-volt battery, allowed to “rest” for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.6 volts between terminals.
What happens when the battery is fully charged?
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their highest level.
Is it possible to add energy to a battery while charging?
Assuming a properly functioning charging circuit you cant add excess energy to the battery. There is no redirrcting of energy, the chaarging circuit just stops drawing power from the charger. Thanks for contributing an answer to Physics Stack Exchange!
What happens if I leave my cell-phone charging all night?
If I leave my cell-phone charging the whole night, it will be fully charged after a while. What happens with the battery and the excess energy I add? Also, I noticed my charger emitting a different pitched sound after it has fully charged the battery. Is this just a mechanism that kicks in to redirect excess energy?
How does a cell phone battery charger work?
Charging your cell phone battery is a complicated process involving a specialized circuit in your phone to provide the correct current to the battery at all levels of charge. How this works is really an electronics question, not physics. The phone does all the hard work, the “charger” just does what it is told.
