What is current electricity in Brainly?
Answer: An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire.
What is our current electricity?
Current electricity is the electricity that powers our homes and electrical devices. Current electricity is named for the way electrons move. They “flow” in one direction – like a river current. The study of electrons in motion like this is called Electrodynamics.
What is an example of static and current electricity?
Two examples of static electricity are lightning and rubbing your feet on the carpet and then touching a doorknob. Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC).
What is electricity explain example?
Electricity is defined as the effects of an electric charge. An example of electricity is the force that powers a light bulb. An example of electricity is lightning. An example of electricity is static electricity, the buildup of electric charges on an object’s surface. noun.
What is electric current answer the following?
Explanation: Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric circuit is called an electric current. The conducting material consists a large number of free electrons which move from one atom to the other at random.
What do you mean by electric current class 10?
Electric Current: The flow of electric charge is known as Electric Current, Electric current is carried by moving electrons through a conductor. … Electric current is expressed by the rate of flow of electric charges. Rate of flow means, the amount of charge flowing through a particular area in unit time.
What is the unit of current?
The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp.
Is lightning static or current?
Lightning is essentially a giant static electricity shock. Both are electric currents connecting the positive charge to the negative charge. Unlike lightning, however, our little shock of static electricity moves from the balloon to the spoon, and not a cloud to the ground.
