what mean by electric circuit?

Answer 1

An electric circuit consisting of a power source, connecting wires or conductors, and a device that uses the electrical energy. The device that uses the energy is called the load. For current to flow in an electric circuit, there must be a complete path from the negative terminal of the power source, through the connecting wires and load, back to the positive terminal of the source. If a complete path does not exist, no current will flow, and the circuit is called an open circuit.

Answer 2

Electric Circuit:
A continuous and closed path of an electric current is called an electric circuit.

Answer 3

A torch light or flash light is a simple electric circuit.When you press the switch electric circuit become complete circuit and current flow into lamp to produce light otherwise circuit is not complete thus no light.

Answer 4

An electrical network or electrical circuit is an interconnection of electrical elements such as resistors, inductors, capacitors, diodes, switches and transistors. It can be as small as an integrated circuit on a silicon chip, or as large as an electricity distribution network.

Answer 5

A circuit is the electrical/physical analogue of a system

Answer 6

If I'm not mistaken...

Impedance = inductance

What goes in has to balance what goes out

At it's simplest, a wire connected to power generates heat to toast bread or photons to give light.

Electrons going IN to do effiecent WORK without BURNING UP or MELTING DOWN and come back out safely.

Put too many OHMS of resistance on an amplifier and it blows out the transistors.

Put too few OHMS of resistance on an amplifier and it burns out the coils on a speaker. It, essentially, fries it.

Put the right amount of OHMS of resistance on an amp and it generates the maximum amount of sound power without burning up transistors or voice coils.

Impedence = inductance

The circuit = the power

The load = the force

It's a balancing act.

Answer 7

Electromotive stress (EMF) while a voltage is generated by ability of a battery, or by ability of the magnetic stress in accordance to Faraday's regulation, this generated voltage has been traditionally referred to as an "electromotive stress" or emf. The emf represents means consistent with unit cost (voltage) which has been made obtainable by ability of the producing mechanism and is no longer a "stress". The term emf is retained for historic motives. that is helpful to tell apart voltages that are generated from the voltage transformations which take place in a circuit as a consequence of means dissipation, e.g., in a resistor.

Answer 8

Hi, the best way to understand this is to actually see or visulize the circuit. I recomend clicking on this site:
http://www.pbs.org/wgbh/amex/edison/sfeature/acdc.html
It will allow you to interact and see how DC/AC circuit works.

Answer 9

An electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, and switches.

Answer 10

a conductive path between two points of different electric charge. This path may pass through resistance and cause one of three effects namely heat, magnetism, and chemical reaction.
