Scientifically, the amount of electricity passing through any section of a conductor in unit time is called current intensity, which is called current for short. It is usually represented by the letter I, and the unit is ampere (André-Marie Ampère).
From 1775 to 1836, French physicist and chemist made outstanding achievements in the research of electromagnetic action, and also made contributions in mathematics and physics.
Ampere, the international unit of current, is named after its surname. The symbol "a" also guides the directional motion of charges in the body.
Through the conductor section? What's the charge? How long will it take to pass these charges? The ratio of is called current, also known as. Current intensity. I = q/T. If the conductor passes within 1s? The charge in the cross section is 1C, and the current in the conductor is1a.
