What is the cause of potential difference?

Electrical energy is transferred to the electrons each time they pass through the battery. The battery may be connected to a circuit with components, such as lamps or resistors. This causes a difference in energy across the component, which is known as an electrical potential difference (p.d.)

What effect does potential difference have on current?

The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.

What is difference between potential difference and current?

The important difference between voltage and current. Voltage is the potential difference between two points in an electric field, which causes current to flow in the circuit. Current is the rate of flow of electrons is called current. Current is the effect caused by Voltage.

Does voltage cause current or does current cause voltage which is the cause and which is the effect?

Voltage is the cause and current is the effect. The voltage between two points is equal to the electrical potential difference between those points. It is actually the electromotive force (emf), responsible for the movement of electrons (electric current) through a circuit.

What is potential difference between two points in electric field what is relation between current and potential difference?

The potential difference between two points in an electric field is one volt, if the work done to move one coulomb of charge between the two points is one joule.

What is the difference between potential difference and potential drop?

Potential drop is the drop along a particular electrical conductor, from source end to utilization end and optimally very small. Potential difference is the potential between two conductors at some location in the system, source or load, or in between.

What is the cause of voltage?

Voltage is the electrical force that causes free electrons to move from one atom to another. Just as water needs some pressure to force it through a pipe, electrical current needs some force to make it flow. Voltage is typically supplied by either a generator or battery.

What causes electric shock current or voltage?

electrical shock, the perceptible and physical effect of an electrical current that enters the body. The effects of electric shock on the human body depend on the current that flows—the amperage—rather than on the force of the current, or voltage.

What is meant by potential difference?

Definition of potential difference : the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.

What is the difference between the cause and effect of current?

You cannot have a current if you do not have a voltage, potential difference, to be exact. So you can gather yourself that voltage is the ‘cause’ and current is the ‘effect’. I guess you have some confusion about some voltage across a current carrying component, say a resistance and you want to clarify things.

What determines the current through a component?

The current through a component depends on both the resistance of the component and the potential difference across the component. Potential difference is a measure of how much energy is transferred between two points in a circuit.

How does the resistance of the circuit affect the current?

The resistance of the circuit has an effect on the size of the current. The current through a component depends on both the resistance of the component and the potential difference across the component. Potential difference is a measure of how much energy is transferred between two points in a circuit.

What is the relationship between current and potential difference?

Hence, the potential difference, V across the conductor increases with the current, I that flows through it. The graph of V against I is a straight-line graph that passes through the origin showing that the potential difference, V is directly proportional to the current, I (V ∝ I). The gradient or the ratio of V/I is constant as current increases.
