Published: 05.05.2021  In the previous section, we explored the relationship between voltage and energy. In this section, we will explore the relationship between voltage and electric field. See [link].

Recall that we were able, in certain systems, to calculate the potential by integrating over the electric field. As you may already suspect, this means that we may calculate the electric field by taking derivatives of the potential, although going from a scalar to a vector quantity introduces some interesting wrinkles. The faster V decreases over distance, the greater the electric field. This gives us the following result.

The change of electric potential with respect to distance is called potential gradient. Acton of Electric field on a Charged Particle When a charged particle is placed in an electric field, it will experience a force which is given by. Let us suppose that an electric field is applied between two parallel plates X and Y kept at a distance d apart as shown in the figure. As the electron on the oil drop has negative charge, the oil drop will experience force in upward direction.

For the oil drop to remain stationary between the plates, the force on oil drop due to the electric field must be equal to the weight of the oil drop,. If a number of electrons are present in the oil drop, then charge Q on it is ne, where e is the charge of the electron.

The number of electrons attached to the oil drop is obtained as. Any surface over which the potential is same is called an equipotential surface. The potential difference between any two points on an equipotential surface is zero. This means no work is done in moving the test charge from one point to the other point on an equipotential surface. It is possible only if the test charge does not experience any force along the equipotential surface.

However, the motion of charge is always perpendicular to the electrostatic surface, when the charge moves on the equipotential surface. Hence, the lines of force, which start normally from a charged conductor cut an equipotential surface everywhere at right angles.

The net electric potential at a point due to a number of charges is equal with the algebraic sum of electric potential charges. V n be the individual electric potential produced at point 'P'.

The relationship between electric potential and field is similar to that between gravitational potential and field in that the potential is a property of the field describing the action of the field upon an object see. Electric field and potential in one dimension : The presence of an electric field around the static point charge large red dot creates a potential difference, causing the test charge small red dot to experience a force and move. The electric field is like any other vector field—it exerts a force based on a stimulus, and has units of force times inverse stimulus. In the case of an electric field the stimulus is charge, and thus the units are NC In other words, the electric field is a measure of force per unit charge.

Physics for Computer Science Students pp Cite as. We have seen in the preceding chapter how the presence of an electric charge has an effect on another electric charge. This raises the question: What if there is only one electric charge present? The idea of an electric field is introduced to describe the effect in all space around a charge so that if another charge is present we can predict the effect on it. If we have multiple charges, such as in Example 13—2, we see that the force of each on a third charge is a vector, and the net effect on the third charge is the resultant of the forces. This resultant will differ with both the position and the charge of the third one. The concept of separating the calculation into the formation of an electric field and the response to the electric field by a given charge placed in it greatly simplifies the calculations.

## The Electric Field and the Electric Potential

Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It only takes a minute to sign up. To place a charge in the vicinity of an electric field, you should do work against the electrostatic force on the charge. Hence electric field is the negative gradient of the scalar potential. The negative sign came as a result because the potential difference is the work done per unit charge against the electrostatic force to move a charge from a to b.

The electric potential also called the electric field potential , potential drop, the electrostatic potential is the amount of work energy needed to move a unit of electric charge a Coulomb from a reference point to the specific point in an electric field with negligible acceleration of the test charge to avoid producing kinetic energy or radiation by test charge. More precisely it is the energy per unit charge for a small test charge that does not disturb significantly the field and the charge distribution producing the field under consideration. By dividing out the charge on the particle a quotient is obtained that is a property of the electric field itself. In short, electric potential is the electric potential energy per unit charge.

### Electric Potential in a Uniform Electric Field

Electric potential energy , or Electrostatic potential energy , is a potential energy measured in joules that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An object may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged objects. The term "electric potential energy" is used to describe the potential energy in systems with time-variant electric fields , while the term "electrostatic potential energy" is used to describe the potential energy in systems with time-invariant electric fields. The electric potential energy of a system of point charges is defined as the work required to assemble this system of charges by bringing them close together, as in the system from an infinite distance.

The change of electric potential with respect to distance is called potential gradient.

For the oil drop to remain stationary between the plates, the force on oil drop due to the electric field must be equal to the weight of the oil drop,. - Но я не думаю… - С дороги! - закричал Джабба, рванувшись к клавиатуре монитора.  - Это и есть ключ к шифру-убийце. Разница между критическими массами. Семьдесят четыре и восемь десятых. - Подождите, - сказала Сьюзан, заглядывая через плечо Соши.  - Есть еще кое-что.

Выходит, нас атакует всего лишь первый набросок червя Танкадо. - Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом. - Не верю, - возразила Сьюзан.

Вы хотите дать взятку представителю закона? - зарычал. - Нет, конечно. Я просто подумал… - Толстяк быстро убрал бумажник.  - Я… я… - Совсем растерявшись, он сел на край постели и сжал руки.

Это случилось во время поездки на уик-энд в Смоки-Маунтинс. Они лежали на широкой кровати под балдахином в Стоун-Мэнор. О кольце он позаботиться не успел, слова пришли сами . - Это совершенный квадрат. - Совершенный квадрат? - переспросил Джабба.  - Ну и что с .

Я заплачу ему десять тысяч долларов за один день работы. Он заберет личные вещи Танкадо и вернется домой. Разве это не услуга. Сьюзан промолчала.

Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод. - Сьюзан! - рявкнул голос у нее за спиной. Она в страхе повернулась, думая, что это Хейл. Шестиэтажная ракета содрогалась.
