What is electric current and circuit?
An electric current is a flow of charge, and in a wire this will be a flow of electrons. We need two things for an electric current to flow: something to transfer energy to the electrons, such as a battery or power pack. a complete path for the electrons to flow through (an electric circuit )
What is electric current for class 10th?
Electric current is rate of flow of electric charge or the amount of charge flowing through a particular area in unit time. … In reality, electric current is flow of negatively charges particles called electrons. These flow from negative terminal of the battery to the positive terminal.
What is the difference between electric current and circuit?
Electrical current is a measure of the amount of electrical charge transferred per unit time. An electric circuit can be defined as a closed path through which electric current can flow. …
What is electric current?
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. … The SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second.
What is electric current short answer?
An electric current is a flow of an electric charge between two points. Imagine it being like water in a river carrying energy. The electric charge in the electrons causes resistors in light bulbs and electric fires to heat up. It also creates magnetic fields in motors, inductors, and generators.
How can we define current class 10?
Answer: Explanation:Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms.
