Explain electric current nd it's SI unit . for 3 marks question.?

Question

Answer

The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit[5]:15 Electric current is measured using a device called an ammeter.[2]:788

Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators.

The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.

Answer

Electric current ---> The rate of flow of electric charge is known as electric current.

# Formula ---> I=Q/T.
# SI unit ---> Ampere(A).
# Definition of SI unit of electric current (Ampere)=> One ampere is constituted by the flow of one coulomb of charge per second.
# Formula of ampere -->1A=1C/1s.

££ Small quantities of current are expressed in milliampere(1 mA=10^-3 A) or in microampere.

hope it's help u :)

Answer

Electric Current and its SI Unit

Electric current is defined as the flow of electric charge in a circuit. It is the rate of flow of charged particles like electrons or ions in a conductor. The current is measured in amperes (A), which is the SI unit of electric current.

Definition of Electric Current

Electric current is defined as the rate at which electric charge flows through a circuit. It is the amount of charge passing through a given area per unit time. The direction of electric current is taken as the direction of flow of positive charge. But in reality, electric current is due to the flow of electrons, which are negatively charged particles. The current flows from a high potential to a low potential, and the magnitude of current is directly proportional to the potential difference between the two points.

Formula for Electric Current

The formula for electric current is given as:

I = Q/t

Where I is the electric current, Q is the charge flowing through the circuit and t is the time taken for the charge to flow.

SI Unit of Electric Current

The SI unit of electric current is ampere (A), which is named after the French physicist Andre-Marie Ampere. One ampere is defined as the flow of one coulomb of charge per second. It is a base unit in the SI system and is used to measure the flow of electric current in a circuit.

Conclusion

Electric current is the flow of electric charge in a circuit, and it is measured in amperes. The direction of current is taken as the direction of flow of positive charge, but in reality, it is due to the flow of negatively charged particles. The SI unit of electric current is ampere, which is defined as the flow of one coulomb of charge per second.

Answer

An electric current is the rate of flow of electric charge past a point or region.

* Formula---->I=Q/T

* SI Unit----->Ampere(A)

HOPE ITS HELPFUL :) :)

https://edurev.in/question/540516/what-do-you-mean-by-electric-current-and-what-is-i

Answer

The amount of electric charges flows through a conductor per unit time is called electric current. Its SI unit is Ampere named after the French scientist, Andre Marie Ampere. 1 Ampere of electric current is the flow of 1 coulumb of charge per second. Electric current in a circuit is measured by an instrument called ' Ammetre'. Smaller quantities of current are measured in 'Milliampere or microampere or nanoampere'

Answer

The rate of flow of charges through a conductor wire is called electricity. The s.i. unit of electric current is Ampere.
I = Q / t
l = electric current
Q = charge
t = time taken
