Electric Current Definition: Electric current is defined as the flow of charged particles—such as electrons or ions—through a conductor or space. Electric Current Formula: The flow rate of electric charge is calculated by dividing the change in charge by the change in time. Electric Current Uni...
The rate of the flow of electrical charge particles (q) passing through the cross-section areas of the conductor in the time (t) is called as Electric Current. This formula states that when one-coulomb charge particle flows in one second, the one-ampere current is produced in the circuit....

Electric Current Lesson for Kids from Chapter 6/ Lesson 28 34K Electricity is produced when an electric current runs through a circuit. Learn about the discovery and different types of electricity, and explore the definition and role of electric current in series and parallel circuits. ...
What is an electric dipole? Electrostatic Electrostatic is a branch of physics that deals with charge or electrical charges that are stationary or not moving which is opposite to a current. Electrostatic phenomena exist when two objects that are charged interacts with each other like a comb and ...
A capacitor is a passive electrical component that can store energy in the electric field between a pair of conductors (called “plates”).In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also ...
Voltage Formula 2 (Power And Current) The power transferred is the product of supply voltage and electric current.Now, put in the above equation we get, (1) Thus, we get voltage equals the power divided by current. Mathematically,Example...
Understanding the electric power formula will help teams increase efficiency and make better, more informed decisions about the use of electrical energy. The electrical power formula is:P = V x I In this equation, I is the electrical current, V is the voltage, and P is the total electrical...
An electric charge produces an electric field, which is a region of space around an electrically charged particle or object in which an electric charge would feel force. The electric field exists at all points in space and can be observed by bringing another charge into the electric field. How...
Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire but can also flow through semiconductors,insulators, or even through a vacuum as in electron or ...
