at this point nothing has happened... you basically have extended the circuit... except it is still an open circuit... until the circuit is closed electricity doesnt move... the moment you close the circle or circuit(like by attaching your phone) then the electricity can flow... electricity needs a complete path(like a circle) to work

Why does my home AC charger charge my iPhone so much faster than my automobile DC charger?

Phone will charge faster with a larger charging current. Charging current depends on voltage, so your home charger likely has a higher voltage and therefore a higher charging current.


Why does a cell phone charger drain a battery?

As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it). The real issue is now fast the charger is draining the battery. BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).


Show me the Circuit diagram of the charging system of the phone?

I am mot so sure.


How much does it cost to recharge a cell phone battery?

Only running cost is the cost of electricity consumed to charge the battery through a charger. How many units of electricity is consumed will depend on the capacity of battery, efficiency of the charger (and so losses of energy in the charger in form of heat and radiation). You can estimate the power consumed by the voltage and wattage rating of the charger and how long it takes to charge the phone battery fully. - Neeraj Sharma


How much voltage does a mobile charger need?

My mobile phone (an Alcatel) charger will supply 500 mA at 5 V. So the maximum continuous power it is capable of supplying will be the product of these two -i.e. 2.5 W. Of course, it won't necessarily ever reach that value in practise.

How do you charge a Samsung reality?

Ok, this is hard. You take the Samsung phone charger that came with the phone, put the outlet end into the outlet, and the mouth (in other words phone plug for the dumb people reading this) of the charger into the phone, and that's it! You are now charging your Samsung Reality!

How to charge a cell phone?

To charge a cell phone you will need either an outlet plug-in or car charger compatible with your particular model. The best way to fully charge a cell phone is to turn it off completely while charging. At the butt of the cell phone there should be a thin slot to plug your cell phone charger into. Plug the other end of the charger into your wall or car's cigarette lighter.


When you are charging your phone and its done charging and you forget will your phone mess up?

No it wont you can keep it on the charger for 100 days


When charging a cell phone should you plug in wall outlet first?

It really does not make much of a difference. However, I would plug in the charger into the cell phone first, THEN into the AC power socket/outlet. The reason why is that it is usually harder to attach the charger plug into the phone. If you're pushing it in and it doesn't fit, you're making a partial connection. This may tax the power protection circuitry in the phone, because the charger is already plugged into the wall. So, best to plug it into the phone first, then into the wall.


Why does a cell phone charger continue to consume power when plugged into an outlet but not the phone?

Most electronics will consume a little power even if they are off or not in use. In the case of a cell phone charger, you may notice that if it is plugged into the wall, but there is no cell phone charging, the charger will still be warm. I don't know the physics behind that, but anything that is plugged in will take up a little energy, even when not in use.


How long does it take to charge a portable charger?

This depends on what kind or charger are you asking about and what kind of battery are you charging. My Phone charger takes two hours to charge my phone.
