How do you measure current?!
The ampere is a basic unit in the international system of units. An ammeter is an instrument for measuring current. Nature has many kinds of carriers loaded with charges, such as electrons in the conductor, electrons in the electrolyte, electrons and ions in the plasma, quarks in hadrons.
It is not necessary to shorten the two side, because the two side always meets the ammeter. I need to use a multimeter to test, as long as the first to properly connect the multimeter alternating current file (not simply use the pen, then contact) Kaiyuan fault current meter line can be. After the measurement is completed, the original ammeter is restored and the multimeter is removed.
Want to measure the current of a part, disconnect a part of the circuit, the ammeter into the circuit, read the current on the degree is the current
An electric current is a flow of electric charges. The magnitude of the current is called the current intensity. It refers to the amount of charge that passes through a cross section of the wire per unit time, and is called a ampere per second through a Coulomb amount of electricity (Ampere).
