Magnetic field

Using the method used has previously Using the method previously used already, we can compare the phenomenon prosperous electric current to flow through a tube. We define the flow of water expressed in liters of water flowing per unit time. Electricity is, as we know, the flow of electric charge. Electricity flowing in, we will define the unit of time (1 second) the quantity of electric charge, expressed in units of measurement called Lombardi The ratio between the quantity of electric charge until we call the intensity of the current mark and the letter I as the intensity of the current practice adopted by Amer 1 (A). The intensity of the current one Ampere present value of the electric charge of one coulomb (1 C) for one second. Cargo 1 coulomb contains 6 290 000 000 000 000 000 electrons. Besides Ampere (A) to denote the intensity of the current is also used smaller or larger units from one Ampere Here are some examples of the size of those of the intensity of the current practice:- Weather (pioneer) about 200 000 A- Furnaces for smelting metals around. A 100 000- Starting a car with room air temperature of approximately 100 A- A refrigerator electric 6- Incandescent lamp 60 W 0.27 A
