I have it written down in my notebook like this: Potential difference is electrical energy produced by the cell. Voltage is the amount of energy used by a component lightbulb. Are they correct?

Electric Potential: The amount of electric potential energy at a point is called electric potential.

What is Voltage or Potential Difference ?

The required amount of energy to move the unit charge from one point to another is known as Voltage. In other words, voltage is defined as the difference between electric potentials. EMF or Electromotive Force is the energy supply to the charge by a battery cell. In other words, EMF produces and maintains voltage inside an active cell and supplies energy in joules to each unit of coulomb charge. EMF is the maximum potential difference between two points of the battery when no current is flowing from the source in case of open circuit.

3.2 Electric Potential and Potential Difference

Voltage , electric potential difference , electromotive force emf, electric pressure or electric tension is the difference in electric potential between two points, which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. In the International System of Units , the derived unit for voltage potential difference is named volt. The old SI definition for volt used power and current ; starting in , the quantum Hall and Josephson effect were used, and recently fundamental physical constants have been introduced for the definition of all SI units and derived units. Electric potential differences between points can be caused physically by electric charge build up or imbalance eg. These latter processes at microscopic level have the physical origins previously mentioned.

Recall that earlier we defined electric field to be a quantity independent of the test charge in a given system, which would nonetheless allow us to calculate the force that would result on an arbitrary test charge. The default assumption in the absence of other information is that the test charge is positive. We briefly defined a field for gravity, but gravity is always attractive, whereas the electric force can be either attractive or repulsive. Therefore, although potential energy is perfectly adequate in a gravitational system, it is convenient to define a quantity that allows us to calculate the work on a charge independent of the magnitude of the charge. Keep in mind that whenever a voltage is quoted, it is understood to be the potential difference between two points.

На стене криво висело баскетбольное кольцо. Пол был уставлен десятками больничных коек. В дальнем углу, прямо под табло, которое когда-то показывало счет проходивших здесь матчей, он увидел слегка покосившуюся телефонную будку. Дай Бог, чтобы телефон работал, мысленно взмолился Беккер. Двигаясь к будке, он нащупывал в кармане деньги. Нашлось 75 песет никелевыми монетками, сдача от поездки в такси, - достаточно для двух местных звонков.

 Премного благодарен, приятель! - крикнул тот ему вслед.  - Увидишь Меган, передавай от меня привет! - Но Беккер уже исчез. Двуцветный вздохнул и поплелся к танцующим. Он был слишком пьян, чтобы заметить идущего следом за ним человека в очках в тонкой металлической оправе. Выбравшись наружу, Беккер оглядел стоянку в поисках такси. Ни одной машины.

Джабба облегченно вздохнул.

Сьюзан смотрела на эти кадры, то выходившие из фокуса, то вновь обретавшие четкость. Она вглядывалась в глаза Танкадо - и видела в них раскаяние. Он не хотел, чтобы это зашло так далеко, - говорила она.  - Он хотел нас спасти. Но снова и снова он протягивал руку, так, чтобы люди обратили внимание на кольцо.

 Но… офицер ничего не сказал о… - Разумеется. Я не сказал ему про спутницу.  - Взмахом руки Клушар величественно отверг вопрос Беккера.  - Они не преступницы - глупо было бы искать их, как обычных жуликов. Беккер все еще не мог прийти в себя от всего, что услышал.
