Why the current not flowing through the wire when one end is connected to the positive terminal and the other end is let open why the positive potential does not affect the electrons in the wire?

since it is not grounded ,it does not accept the flow of current

In a dry cell the carbon rod releases electrons and becomes the positive or negative terminal?
In a dry cell, the carbon rod is the positive terminal, or anode.
What terminal does electrons flow from in a dry cell?
That is a good way to run the cell down quickly. Electrons are negatively charged so they always move from the positive terminal towards the negative. Each electron carries a charge of 1.602 x 10-19 coulombs so 1 coulomb (1 amp for 1 second) carries 6.24 x 1018 electrons.
Is conventional flow or electronic flow true?
Electronic flow is true. Conventional flow was thought to have positive charges flowing from the + terminal to the - terminal. This was before we knew that it is actually the electrons which flow, and the positive charges cannot move out of their atomic nuclei. Now that electrons have been detected, and protons are known to stay within the nucleus unless a nuclear reaction takes place, we know that it is the electrons that flow from the - terminal to the + terminal. This is known as electronic flow.
What causes current to flow what makes it do this?
the basic cause of current flow is the movement of electrons ,basically when some potential difference is applied between any two terminal of a wire electrons will flow from low potential to higher potential because of the negative charge possessed by them , further rate of flow of chargei.e., electrons correspond to the electric current with respect to time.
Why is the direction of diodes in alternator diode trio is opposite to the direction of diodes in the rectifier bridge?
A three phase alternator will have six diodes in the rectifier bridge, three with their anodes connected to the phases, and cathodes commoned to the positive terminal, and three with the cathodes connected to the phases, and anodes commoned to the negative terminal, which is likely the housing of the alternator. The trio diodes arrangement will match the positive rectifiers, i.e. anodes to the phase connections, cathodes (denoted usually by a stripe around the body on small diodes), connected to the D+ terminal
Do electron tend to move a region of high potential or lower potential?
Electrons always move 4m a region of low potential 2 higher. While electrons move 4m negative 2 positive terminal they continuously gain energy as work is done on them by the positive terminal to attract them 2wards it. In this process an energy equal to the work done on the electrons ( by the positive terminal ) is gained by the electrons. That is y, as electrons cum closer to the positive terminal they hav high potential stored in them..The electrons, in order to attain this high potential flow 2wards the positive terminal of a battery wen connected in a circuit... Answered by - a 10th standard boy....:D...........
What does the positive side of the battery do?
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Which battery cable should be reconnected first?
Positive should always be connected first. The pull of electrons toward the positive terminal will cause a spark.
Why positive terminal has the higher potential?
Just arbitrary choice by Benjamin Franklin when he defined "conventional" electric polarities.The negative terminal has higher number of electrons, but Franklin knew nothing of electrons as they were not discovered until more than a century later.Mathematically it makes no difference whether the positive terminal or negative terminal has higher potential, as long as one is consistent one way or the other in the equations.
How current flow from positive to negative terminal in cell?
DC current. Some experts argue that indications show that electrons flow from negative to positive (According to current arguments), but it is assumed generally that electrons flow from positive to negative.
Which terminal of bulb does connect with battery?
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
Why the dc average voltage is having negative value?
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
What is the positive terminal of the battery called?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.

Why do you not get battery symbol on your laptop sometimes after you on power supply in your laptop made by Toshiba model no A200?
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
