In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?

Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.

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...........
Is it correct to say that an electric current is used up as it passes through an electrical component?
No. No more than water is used up as it passes through a pipe. In almost all circuits, for every electron that leaves the negative terminal of the battery and flows into the circuit, an electron returns at the battery's positive terminal. Each electron is completely spent, exhausted, limping, semi conscious, completely empty of energy and barely able to stagger to the finish line, but the number of electrons ... the amount of current and the amount of charge ... is not 'used up'.
What reduces the flow of current?
In a conventional current, the electric field points the way decreasing electric potential goes. The current from the positive terminal is at a higher potential toward the negative terminal, which means the current is in the direction of decreasing potential.
What is the terminal potential in the short-circuit?
in the case of short-circuit the current is maximum hence the terminal potential is becomes zero
What is the definition of terminal energy?
In hunting, terminal energy is the force of impact by a projectile (bullet) with its target. In biology, a terminal electron acceptor is a compound that receives or accepts an electron during cellular respiration or photosynthesis.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
What is an electron's role in a circuit?
Everything that goes on in an electrical circuit happens in response to a flow of electrical current. Electrons are the carriers of electrical charge whose motion constitutes the electrical current in the circuit.
What is called energy of electron at its negative terminal of battery?
ENERGY
The terminals of a diode are called the?
anode positive potential cathode negative potential
If an electron gun electron is moved with electric potential of 9000 volt.then What will be the energy of electron in electron volt?
If an initially stationary electron falls through 9,000 volts of potential difference, then it arrives at the positive terminal with 9,000 eV of energy.
How does potential difference make an electric current flow and what is the direction of that current?
Potential difference, voltage, is a force that will cause electrons (negative charges) to move if they can. Voltage is the motive power behind electron flow, and electron flow is the current. In a battery, we have voltage between (or across) the terminals from chemical energy inside. We don't have to have current flow to have the voltage. Some might think of voltage as "electrical pressure" because it is a force. That isn't a bad way to look at it. If we connect some wires and put a light bulb and a switch in series across the terminals of the battery, we have a circuit. If we close the switch, voltage, which was present all the time, will now cause electrons to flow through the wire and light the bulb. The battery has a positive terminal and a negative terminal. The positive terminal will take in electrons and the negative terminal will send them out. Current flows in only one direction. The potential difference created by the battery has energized the circuit and current flowed from the negative terminal of the battery, out through the circuit, and back to the positive one.
What energy is the flow of electrons?
current :))))
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 a open cicuit?
An open circuit is a situation when there is no electrical path from the positive terminal to the negative terminal (in case of DC) or from the live terminal to ground (in case of AC)

Does terminal negative and ground same?
Normally they are used as if they were same but ground means that this connection is linked to earth, negative means that this connection is linked to a negative terminal. It is possible that someone has named the terminal incorrectly and named it ground instead of negative. Voltage between negative terminal and ground is normally 0, that means that they are on the same potential and that there is no danger of short-circuit.
