Basically, one option - for providing energy to a circuit - is a cell or battery; the other option is to connect the circuit to an electrical outlet. With a cell, the current will be DC; with an electrical outlet, it will be AC (alternating current, that is, the direction of the current changes several times per second). You should also keep in mind the voltage - household current has a fairly high voltage (110 or 220 volts), compared to a cell (typically around 1.5 volts) or even a car battery (usually 12 volts).

What parts of the cell are used to connect an electrochemically cell to a circuit?

Is it necessary to have cell in electric circuit?
A cell basically works as a producer of a potential difference in the circuit which is necessary for the electrons to travel in a region. Therefore using this principle we can understand that almost anything that can produce a PD can be used in an electric circuit. The best example would be of emf through EM induction of the Faraday's experiment
What is a cell in a circuit?
The function of a cell in an electrical circuit is to push the lectrons around the circuit. It can also be the source of charge in an electrical circuit.
What is responsible for lost volts of a cell?
A cell has internal resistance, which means that some of the potential(voltage) it provides is used up just in getting current out of the cell and into the circuit.
What is the direction of flow of current in a cell?
Current doesn't flow inside the cell. The cell is used to push current through an external circuit. The so-called "conventional" current flows out of the positive terminal of the cell, through the circuit, and back into the negative terminal of the cell. The confusing truth is that the actual physical carrier of current is the electron, which carries a negative charge. So the things that are actually moving and carrying the current through the circuit leave the dry cell from its negative terminal, physically flow through the circuit, and end up at the cell's positive terminal.

How a cell is essential in a circuit to provide energy for lights and motors?
In a circuit, a cell acts as a power source by providing electrical energy to power lights and motors. It converts chemical energy stored within it into electrical energy that can be used to produce light in bulbs or generate motion in motors. The flow of electrons from the cell through the circuit is what ultimately powers these devices.
What term is used for the energy transferred by a cell to the current?
The term used for the energy transferred by a cell to the current is "voltage." It is the potential difference created by the cell's battery that drives the flow of electrons through a circuit.
What parts of the cell are used to connect a electrochemical cell to a circuit?
The nodes of the electrochemical cell are called the electrodes. The Cathode is the + end (of a battery). Negative charge enters through it. The - end is called the anode.
What is an electric circuit what is it used for and where would you find one?
Electric circuits are everywhere. In your car, home, office, your digital watch, your cell phone and on and on. The electric circuit that makes up your cell phone provides the local user interface and connects to a cell tower to allow you to make and receive calls.
What is a pre owned cell phone?
A pre-owned cell phone is a "used cell phone," one that was previously used by someone else. They probably traded it in when they upgraded to a newer model. It is the same as a pre owned car or "used car."
Are there used cell phone dealers online?
Yes, there are several used cell phone dealers online. The best place to search for a used cell phone is Ebay. They have used cells phones for the cheapest price.
