An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.
Electrical potential difference is the change in electrical potential energy per unit charge. For example suppose you move 10 Coulombs of charge from point A to point B and its potential energy increases by 500 Joules (because of other nearby charges). Now it is convienent to divide that potential energy change by the amount of charge that was moved 500/10 = 50 Joules/Coulomb. This is called the potential difference between A & B , or voltage across AB. This is a bit abstract but potential difference gives you a measure of potential energy possibilities without specifying any particular amount of charge. Once you have the potential difference, or voltage, you can calculate how much potential energy any amount of charge would have acquired simply by multiplying that charge times the potential difference. So in the above example the voltage across AB is 50 volts. How much potential energy would 40 Coulombs of charge aquire if moved from A to B. Answer; charge x voltage = 40 x 50 = 2000 joules. Once again, the usefullness of potential difference, or voltage, is that it gives you a "measure" of the potential energy that charges might gain (or lose) without actually calculating the potential energy for a specific amount of charge.
The work to be done to bring a unit positive electric charge from infinity to the given in an electric field is known as the electric potential at that point.
the electric potential at a point in an electric field is defined as the work done in moving a unit of positive charge from infinity to that point,
It is the electrode potential when it is single
Abillty to conduct movement of electrons in order to transfer electric energy.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit.
A reference electrode is maintained at a certain potential, for comparison by other electrodes.

To determine electrode potential
To determine electrode potential
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.
The single electrode potential comes from electrodes.
Electrode potential is the voltage that an electrode is at. This has to be measured versus a reference electrode
Standard electrode potential is a redox electrode. This is the forms the basis of the thermodynamic scale.
246 mV
A reference electrode is maintained at a certain potential, for comparison by other electrodes.
When the reduction electrode potential of the metal electrode increases there will be a tendency towards corrosion.
The electrode with the highest oxidation potential
It depends on the electron configuration. Different metals have single electrode potential. They are both +ve and -ve. We use standard Hydrogen electrode whose potential is taken to be 0. Using that we can find half potential. Then right from that we get the total potential of a cell. So it is all natures work
is a theory used in electrochemistry that relates the potentials and currents from differing constituents to come up with a 'weighted' potential at zero net current. In other words, it is an electrode potential resulting from a simultaneous action of more than a single redox couple, while the net electrode current is zero.
The open circuit (oc) potential is the potential of the working electrode relative to the reference electrode when no potential or current is being applied to the cell.
A reference electrode is an electrode with a well-known electrode potential. Its main function is to serve as a half cell to build an electrochemical cell.
