How much work is required to carry an electron from the positive terminal of a 4 V battery to the negative terminal?
As
W=qv
So, w=(-1.6×10^-19)(-12)
(here q is negative because its about electron we know that electrons and protons have same magnitude and apposite signs)
Therefore w=1.9×10^-18

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?
The electrical potential energy of an electron leaving the negative terminal of a 1.5V battery would be 1.5 electronvolts (eV). This energy is gained by the electron as it moves through the circuit towards the positive terminal.
USing the theory called electron flow concept means that electrons flow from?
The electron flow concept states that electrons flow from the negative terminal to the positive terminal of a voltage source, in contrast to the conventional current flow theory which assumes positive charge carriers moving from positive to negative.
How do you know positive and negative terminals?
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
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.
The flow of current in electrodes is in which direction?
The flow of current in electrodes is from the negative electrode (anode) to the positive electrode (cathode). This flow is conventionally considered as the direction of electron flow.
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.
Does energy flow through the negative or positive of a battery?
Energy flows from the negative terminal to the positive terminal of a battery.
Why is it necessary that an electron returns to the positive terminal of the battery each time another electron leaves the negative terminal?
Electrons flow from the negative terminal to the positive terminal of a battery due to the potential difference created between the terminals. This movement of electrons completes the circuit and allows for the continuous flow of current, enabling the battery to provide power to electrical devices.
What happens when you inadvertanly crossed the positive battery terminal from a negative to a positive and a positive to a negative.?
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
What is positive about batteries?
One terminal is positive and the other terminal is negative. The positive terminal is slightly larger.
What does the negative terminal of a battery have?
The negative terminal of a battery has a - sign and positive terminal has a + sign.
Does the positive end of a battery go to the positive or negative end of the terminal?
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
