E: As you said, it is the ELECTRIC potential.
M: Look up the definition of motive. It has a use in physics too.
F: Although it is not the typical "force" that you think of (a force represented by a vector field), it is a force, just one represented by a scalar field.
Does this answer your question?
I believe so. However, the scalar field, to my understanding, is measuring the potential energy of the interaction in volts. I am not an expert on bateries, however I believe it is just a normal electric potential, and in that sense it doesn't mater if chemicals do or don't play a role.tonyjk said:Hello Isaac,
I read that the battery stores its potential energy in a chemical form. It means that the chemical reaction in both cells is creating the separation of charges thus storing or creating potential energy?
A galvanic cell, also known as a voltaic cell, is an electrochemical cell that uses a spontaneous redox reaction to produce electrical energy. It consists of two half-cells, each containing an electrode and an electrolyte solution, connected by a wire and a salt bridge.
The redox reaction in a galvanic cell causes a flow of electrons from the anode (the electrode where oxidation occurs) to the cathode (the electrode where reduction occurs) through the external circuit, creating an electrical current. The salt bridge completes the circuit by allowing ions to flow between the two half-cells, maintaining charge balance.
A galvanic cell produces electricity through a spontaneous redox reaction, while an electrolytic cell uses an external source of electricity to drive a non-spontaneous redox reaction. In other words, a galvanic cell is a source of electrical energy, while an electrolytic cell is a consumer of electrical energy.
Electric potential, measured in volts, is a measure of the difference in electrical potential energy between two points in an electric field. In a galvanic cell, the potential difference between the two half-cells is created by the difference in chemical potential energy of the reactants and products in the redox reaction. This potential difference, known as cell potential, is the driving force for the flow of electrons and the production of electricity.
The electric potential of a galvanic cell is affected by several factors, including the nature of the electrode materials, the concentration and temperature of the electrolyte solutions, and the overall cell design. The standard cell potential, which is the potential when all components are at standard conditions, can be calculated using the Nernst equation, which takes into account the effects of concentration and temperature.
