Electricity Today an integral part of the people's passage, without which the further existence of humanity is not imagined. Therefore, each of us should have at least the minimum concept of such a section of physics as a current. Below you will find what it is, in which it is measured, and why this indicator is needed.
What is the current current?
From school lessons of physics, the theory is still remembered that the directional movement of charged particles in any conductor is current. If you explain the audible language, the current force is the number of charged particles that move on the conductor site for a certain period of time. In other words, in 60 minutes, by different conductors, a different amount of electrically charged particles can move (greater, less), respectively, the current power in the conductors is different.
Current force measurement unit
It is denoted by the power of the current Latin letter І, and the unit of measurement of the ampere (A).
Ampere is a reference indicator that is equal to 1 electricity pendant in 1 second. In other words, the power of electric flow is calculated by the number of electricity passes in one second.
To measure the current strength, the number of particles flowing through the transverse cut during a certain period of time are measured. After the result, the result is divided by the measurement time. In the electrical network, the current will be the same anywhere.
How is the current power measured?
To measure the current force, there is a special apparatus, which is called an ammeter. It is demonstrated in the lessons of physics in electrical systems. If you are not a happy owner of such an appliance, but you need to measure the strength of the current of household appliances, you can use the usual arithmetic.
All household appliances are prescribed their power, which is indicated in wats (W). For example, what should be the current for the operation of the kettle with a capacity of 1000 W? As you know the operating voltage of 220V power grids. If you split the power to the voltage (1000/220), we obtain 4.5 A. for the operation of the electrical appliance requires the power of 4.5 A.
