Answer

The SI unit of electric Current -Ampere(A).it is discovered by Andire Marie Ampere in 1820.

Answer

The SI unit of electric current is the Ampere (A). It is named after the French physicist Andre-Marie Ampere, who discovered the relationship between electric current and magnetism in the early 19th century.

Discovery of Ampere and the SI unit of electric current
- Andre-Marie Ampere conducted experiments that led to the formulation of Ampere's Law, which describes the magnetic field produced by an electric current.
- He found that two parallel wires carrying electric currents attract or repel each other, depending on the direction of the currents.
- Based on his experiments, Ampere was able to quantify the relationship between electric current and magnetism, which laid the foundation for the development of electromagnetism.
- In recognition of his contributions to the field of electromagnetism, the SI unit of electric current was named the Ampere in his honor.

Significance of the Ampere
- The Ampere is a fundamental unit of measurement in the International System of Units (SI) and is used to quantify the flow of electric charge in a circuit.
- It is essential for determining the strength of an electric current and for calculating the power consumption of electrical devices.
- The Ampere plays a crucial role in various fields, including physics, engineering, and electronics, where precise measurements of electric current are required.
In conclusion, the SI unit of electric current is the Ampere, named after the French physicist Andre-Marie Ampere, who discovered the relationship between electric current and magnetism. His groundbreaking work laid the foundation for the development of electromagnetism and has had a lasting impact on the field of physics.
