What is an amp?

In everyday life, we use every dayelectricity, but, if necessary, do not know how to measure the current. What is an amp? Ampere is the unit of electric current strength, the main one in the system of Cu. This is the force of a constant electric current, during which it flows through 2 parallel rectilinear infinitely long conductors with an infinitesimal cross-section (located without air at a distance of 1 m from each other), an interaction force of 2 x 10-7 occurs between these conductors N. The unit of magnetomotive force and magnetic field strength in the SI system (A / m).

Who is Ampere?

André Marie, 1775-1836., the French physicist, the founder of the basics of electrodynamics. Ampere discovered the law of interaction of electric currents; the first theory of magnetism; also works on the theory of probability, the application of the calculus of variations in mechanics, and others.

What is an Ampere clock?

Ampere hour is the amount of electricity flowingthrough the conductor or the device for 1 hour, if the current value is 1 a. 1a-h = 3600 coulombs. Used to measure the battery's electrical capacity. To measure the amount of electricity used a special unit - Pendant (abbreviated designation K). The pendant is a very small unit and is inconvenient to use because of its large numerical expression.

For practical measurements of electrical capacitanceA larger unit of Ampere-hour was adopted. Amp is connected with other units of measurement: Volt, Ohm and Watts. If a conductor with a resistance of one OM adds a voltage of one volt, a current of one ampere passes through it and the heat dissipates into one WATT.
