Yes. If the termals are connected by wires, charges will flow from one end to the other.

What is the relationship between the direction of current and direction of electron flow in a current-carrying wire?
The direction of current flow is defined as the direction positive charge carriers would flow, which is opposite to the actual movement of electrons (negative charge carriers) in a wire. Electrons flow from the negative terminal of a power source to the positive terminal, while conventional current flows from the positive terminal to the negative terminal.
Would a current be produced if both terminals had the same charge?
Yes. If the termals are connected by wires, charges will flow from one end to the other.
In a dc circuit polarity refers to the direction of which flow?
In the US, it is common practice in a DC circuit to refer to the polarity for which "positive (+) charge" is flowing. Positive charge (current) will flow out of a voltage supply's positive (+) terminal which means positive charge will flow into the (+) terminal of a circuit load (resistor, etc). This is an arbitrary convention and may be reversed in older or foreign textbooks. In such cases all positive (+) references in the previous description would be replaced by negative, (-) notations.
Would AC or DC be better to use when charging a mobile phone to make a call?
Answer: DC. Explanation: A mobile phone is powered by a battery. A battery stores electric charge. When wires connect the two terminals ['+' terminal and '-' terminal], then a current will flow through the wire from the '+' terminal to the '-' terminal. The electric circuits that operate the cell phone (and any other electronic device) require electric current to operate. In order to store electric charge in the battery you must apply DC current to the battery. AC means 'alternating current', which means that half the time the current flows in one direction along the wire that carries the AC, while the current flows in the opposite direction the other half of the time. One cycle of the AC is the total time for the current to flow in both directions. If you tried to charge a battery with AC, during each half of the cycle the current would undo the charging that the previous half-cycle had provided. There are devices that can convert AC into DC. (They are called converters, or rectifiers.) For a device like a cell phone you would plug the converter into the AC electric outlet, and the converter would produce DC coming out of a cable which you would plug into your cell phone to charge the battery. The converter is a relatively simple electronic circuit. If you want to know more about it, then ask. 25August,2008
When do the anodes and cathodes affect the voltage of a battery?
The anodes and cathodes affect the voltage of the battery all the time. Without them, the battery would not work. The anode provides the positive charge or current. The cathode provides the negative charge or electrons. Part of the anode is down in the battery and part serves as a terminal. Part of the cathode is down in the battery and part serves a a terminal.
How does one charge a sealed lead acid battery?
The basic lead acid battery is ancient and a lot of different charge methods have been used. But one way is to charge these batteries at a float voltalge of 2.25 to 2.3 volts/cell (at 25 degrees C) (13.5V to 13.8V for a 12V battery).
What moves in a current?

How current pass in pickle?
A current needs a charge carrier. In biological tissue, such charge carriers would usually be ions, from dissolved salts.
Would a current be reduced if both terminals had the same charge?
If both terminals had the same potential there would be no current flow.
Can you charge an iPod with an onion and Gatorade?
No, you cant charge an ipod with an onion and gatorade. Mythbusters, and even ABC news tried it, but it didnt work. Inside a USB connector are all made of the same metal, copper, so no electrochemical reaction would occur and no current would be produced in the first place.
When will there be any current in phase?
Current is always flowing in the phase due to the continuous voltage application. the current in phase can be used when it is given a - ve terminal or earth the current would complete the circuit.
How is the electron flow different from conventional current?
The conventional current direction is the direction in which a positive charge would move. Since electrons are negatively charged, the electrons move (in average) in the opposite direction.AnswerBefore the structure of the atom was understood, scientists such as Benjamin Franklin believed that an electric current was a flow of some sort of mysterious 'fluid' that moved from an area of high pressure to an area of low pressure. The high pressure was considered to be 'positive' pressure and the low pressure was considered to be 'negative pressure'. So, for many years, current was believed to travel from positive to negative, but it had nothing to do with 'a flow of positive charge carriers' because no-one then knew about 'charge carriers'.Even though we now know that (in metallic conductors, anyway) that current is a flow of free electrons from negative to positive, for some weird reason many textbooks still show current as flowing from positive to negative! To differentiate between the two current directions, we use the terms 'electron flow', and 'conventional (or 'Franklinian') flow'.
