# Electric current and current flow

Electric current the flow of electrical charge that transports energy from one place to another measured in amperes (aka amps), where 1 a is the flow of 625 x 10¹⁸ electrons per second, or 1 coulomb per second i= v/r. Electric battery electric battery is a device that converts chemical energy to the electrical energy it consists of two different metal plates and we call them as electrodes. The electric current can be identified as the current that is caused by the flow of charges, in the direction of the charges flow current is defined as the rate of flow of charges through a medium these charges are usually in the form of electrons. But to simply answer your question how does current flow: charges (electrons) inside conductors are pumped around the circuit because of a potential difference the electrons can and do pass through the battery(in the form of anions). Start studying chapter 23: electric current learn vocabulary, terms, and more with flashcards, games, and other study tools rate of electric flow-measured in .

Time-saving video on electric current electric current is the rate of charge flow as charge moves through a conductor electric current is caused by difference in electric potential and always flows from high to low. What is an electric current when you hook up wires to the terminals of a battery, charge can flow and a complete path called a circuit is formed. Electric current definition electrical current is the flow rate of electric charge in electric field, usually in electrical circuit using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. There's been a discussion going on since this following thread: range of frequency of electromagnetic wave how electric current flow through a conductor i need.

Current flow and ohm's law ohm's law is the most important, basic law of electricity it defines the relationship between the three fundamental electrical quantities: current, voltage, and resistance. An electric current is a flow of electric charge in a circuit more specifically, the electric current is the rate of charge flow past a given point in an electric circuit the charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes. An electric current is simply a series of electrons which travel down a conductor, most commonly a wire the behavior of electric currents can be understood by analogy of water flowing in a pipe. Electric current flows from a high elecric potential to a low electric potential in a circuit it is also opposite to the direction of the flow of electrons. This force is responsible for the flow of charge through the circuit, known as the electric current key terms battery : a device that produces electricity by a chemical reaction between two substances.

But we define electric current to be the opposite direction of electron flow there’s some good history on why it’s defined this way, but i’m too busy to find it right now — if someone has a good link, stick it in the comments, thanks. Electric current is the rate of charge flow past a given point in an electric circuit, measured in coulombs/second which is named amperes in most dc electric circuits , it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by ohm's law . Hiii, i was wondering if i can get the electric current flow on a 2d surface say there is a rectangle i want to give current at one corner and take out the current from the opposite corner and see the current distribution on the rectangular surface. Current is the flow of electrons in a circuit or electrical system you can also think of current as the quantity, or volume, of water flowing through a water pipe .

## Electric current and current flow

Electric current an electric current [1] is usually thought of as a flow of electrons when two ends of a battery are connected to each other by means of a metal wire, electrons flow out of one end (electrode or pole) of the battery, through the wire, and into the opposite end of the battery. Current is steady it is guided along the conducting wire the transient effects after the switch is closed move from the switch along the whole lengths of the connecting wires. Current is the flow of electrons in a circuit or electrical systemyou can also think of current as the quantity, or volume, of water flowing through a water pipe electrical current is measured in amperage,. The electrons moving through the wire are called the electric current which is measured in amperes, or amps for short that's about as simple as i can make the explanation voltage is the pressure, and current is the number of electrons per second that go through the wire.

• Electron flow vs current flow “in the past when i taught electricity i always understood that it flows from the negative terminal to the positive.
• Electric current formula the rate of flow of charge through a cross section of some region of a metallic material is called the electric current it is related to the resistance of the material and the voltage applied to move the charge.

The current that flows into a junction is always equal to the current that flows out of the junction therefore, current must always flow in a loop share | improve this answer. Originally answered: how does current flow whenever difference of electrical potential is created across the ends of any conductor material the electric current flow through the conductor when the electrical potential difference is created, due to the electric field the free electrons of conductor will experience a force in a particular . Electric current is the flow of electrons, but electrons do not jump directly from the origin point of the current to the destination instead, each electron moves a short distance to the next atom, transferring its energy to an electron in that new atom, which jumps to another atom, and so onthe individual electrons do not move quickly, but the current itself moves at the speed of light. The definition of a current is a collection of moving charges hence for current to flow, one needs charge and one needs it to move one gnerally aciees this on earth with a conductor and a .
