- Hint: SI unit of current is ampere. Ampere is used to represent the rate of electron flow in an electrical conductor.
Complete step-by-step solution -
One ampere can be defined as the unit of electric current and that is equal to the flow of one coulomb of charges per second.
Hence, we can say that, one ampere current is the movement of electrons in a second.
Additional information:
Ampere is a unit of electric current and it is denoted by A. It is named after the great Physicist Andre-Marie Ampere. He is considered as the father of electrodynamics. Ampere is one of the basic units of the SI system.
Some other interesting alternative definitions for ampere,
The current, when passing through 1 Ohm resistor, produces a 1 Volt potential difference across the terminals.
A current used to deposit 0.001118 grams of silver from silver nitrate solution.
The most commonly used equipment in laboratories for the measurement of electrical current in Amperes is Ammeter. It is derived from the Ampere meter. It is always connected in series to the load, since it has zero resistance. If it is connected in parallel to the load, it becomes short circuited due to the low resistance. Ideal ammeter doesn’t have any power loss due to the zero impedance. However, ideal ammeters are not practically possible.
Note: Ampere is a unit of flow of electric charges. Ampere second or Ampere hour are the units of electric charges. These are also known as Coulomb. According to the SI units, constant currents are represented in Amperes.
