Voltage and Ampere
The Basic Difference between Voltage and Ampere is that Voltage is the power differential between two points in an electric field. Ampere, on the other hand, measures the intensity of electrical current in amperes.
Voltage is the pressure that a source of electrical energy can exert on electrons in an electrical circuit, thus establishing the flow of electrical current. The voltage is, then, the potential difference between two points of an electric field or a closed circuit.
The greater the potential difference that an electricity source can exert, the greater the voltage in the closed circuit. This potential difference is measured in a unit known as Volts.
The voltage between two points in an electric field is equal to the work that the unit of positive charge must do to move between them. The voltage is independent of the path that the load must travel and only depends on the potential between the two points.
When a conductor is placed between two points that present a potential difference, the electric current will flow, always from the area with the highest potential to the area with the least potential. If there is an absence of a source that generates electricity, the current flow will stop when both points equal their potential.
It is the intensity of electric current expressed in the unit known as amps. The current intensity is nothing more than the number of electrons that can flow through a conductor in a given time.
For the SI or International System of Units, the intensity is measured in amperes, its symbol being the letter A.
You must bear in mind that an ampere is equal to a coulomb or coulomb per second, that is, more or less the flow of 6,241 x 10 18 electrons per second.
Electrical equipment is classified according to its amperage, that is, according to the energy it demands from the network when it is in operation.
When a person is electrocuted, the amount of electricity that passes through his body will determine the severity of the accident and this is determined by the amperage and not the voltage. A small flow of 0.1 to 0.2 A can kill due to its devastating effects on the heart. Some people have survived major shocks because their muscle contractions acted as a shield to protect the heart.
Difference between voltage and amperage
- Voltage is the unit that measures the potential difference between two points in a closed electrical circuit.
- Amperage is the amount of electricity that flows between two points in a closed electrical circuit.
- The potential difference between two points is what allows electric current to flow in a conductor.
- The current intensity is nothing more than the number of electrons that flow per unit time in a conductor.
