- An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the source of electrons.

Construction eTool Dc Circuits. A circuit is a closed loop through which electrons can flow. A direct current (DC) circuit is a type of circuit with direct current (as opposed to alternating current) flowing through it. That is, in a DC circuit, the current flows in one direction.

What Is an Electronic Circuit? The following paragraphs describe a few additional interesting points to keep in mind as you ponder the nature of basic circuits: 1  When a circuit is complete and forms a loop that allows current to flow, the circuit is called a closed circuit. 2  Short circuit refers to a circuit that does not have a load.

What is an Electrical Circuit? 10 most extreme places on Earth. An electrical circuit is a device that uses electricity to perform a task, such as run a vacuum or power a lamp. The circuit is a closed loop formed by a power source, wires, a fuse, a load, and a switch.n other words, when a power switch is turned on, the electrical circuit is complete and current flows from the positive terminal of the power source, through the wire to the load, and finally to the negative terminal.

What is a circuit? A closed switch means that the circuit through the switch is connected. Current flows from the positive side of the power source (for example, the battery) to the loads wired into the circuit and back to the negative side of the power source.

Compare two circuits with batteries of the same voltage, with the same length of wire, made of the same material, but one wire is thicker than the other. The concentration gradient will be the same in both wires.ompare two circuits with batteries of the same voltage, with the same length of wire, made of the same material, but one wire is thicker than the other.

Circuit Breaker A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.Its basic function is to detect a fault condition and interrupt current flow.he circuit breaker contacts are held closed by a latch. As the current in the solenoid increases beyond the rating of the circuit breaker, the solenoid's pull releases the latch, which lets the contacts open by spring action. Some magnetic breakers incorporate a hydraulic time delay feature using a viscous fluid.

- Likewise in a parallel manner; we say that a circuit breaker can control and protect an electrical circuit. An electrical relay is an example of an operating control; it opens and closes the circuit. Circuit breakers are not designed as replacements for relays, operating controls.

- An electrical circuit is any closed loop that allows a flow of electrons in a current to deliver energy or perform work and then return to their source.Material along which electrical current flows freely are called conductors. (e.g. copper-wire) The electrons emit and return to an energy supply.he minimum components that are needed for an electrical circuit to do useful work are:- A battery(or an electricity source), conducting wire from which electricity can flow … , and a resistror(which is anything like lamp, bulb,ceiling fan etc.) !! 5 people found this useful.

Electronic circuit Electronic circuit. An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. To be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data

short circuit short circuit. A path that allows most of the current in an electric circuit to flow around or away from the principal elements or devices in the circuit. Short circuits can cause too much current to flow through one part of the circuit, often causing the circuit to break.

Electricity A circuit is usually made by linking electrical components together with pieces of wire cable. Thus, in a flashlight, there is a simple circuit with a switch, a lamp, and a battery linked together by a few short pieces of copper wire. When you turn the switch on, electricity flows around the circuit.

electric circuit resistance. resistance, property of an electric conductor by which it opposes a flow of electricity and dissipates electrical energy away from the circuit, usually as heat. Optimum resistance is provided by a conductor that is long, small in cross section, and of a material that conducts poorly. Resistance is basically the same for alternating and direct current circuits (see impedance). However, an alternating current of high frequency tends to travel near the surface of a conductor.

- A simple circuit is a circuit containing one voltage or current source in series with, or in parallel with, one load.Since it is a simple circuit, both definitions, series and parallel, are equivalent and mean the same thing.hen the pump is activated the water flows from the bucket, through the pump, and back to the bucket. Anything that interferes with the flow of water shuts off the water flow, called current in electrical circuits. ==== A simple circuit is a battery and a resistor.

What is a circuit? A parallel circuit. A parallel circuit is a circuit in which there are at least two independent paths in the circuit back to the source. In a parallel circuit, the current will flow through the closed paths and not through the open paths. In a parallel circuit the electricity has several paths that it can travel.
