Tell about Electric Currents ?

hi

hello

Conventional Current Direction.

The particles that carry charge through wires in a circuit are mobile electrons.

The electric field direction within a circuit is by definition the direction that positive test charges are pushed.

Thus, these negatively charged electrons move in the direction opposite the electric field.

It has positive and negative charges,

which is expressed in coulomb.

An electrical phenomenon is caused by flow of free electrons from one atom to another

hello

The characteristics of current electricity are opposite to those of static electricity.

An electric current is a flow of electric charge.[1]:2 In electric circuits this charge is often carried by moving electrons in a wire.

Wires are made up of conductors such as copper or aluminum.

Direct current is seldom used as a primary energy source in industries.

. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma)

It mostly used in low voltage applications such as charging batteries

aircraft applications, etc.

Alternating current is used to operate appliances for both household and industrial and commercial use.

The electric current is measured in ampere.

The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.

Simple explanation for these terms can be

Electric current is measured using a device called an ammeter

Charge: Its the "amount" of unbalanced electricity in a body.

Its usually measured in the form of electrons (either excess or deficiency).

Electric currents cause Joule heating, which creates light in incandescent light bulbs
