Electrolytic Corrosion

Electrolytic Corrosion Removal Protection

Electrolytic corrosion is created by contact between two different metals in a damp atmosphere with dust or pollution of a type that will dissolve in water. Precautions may have to be taken to ensure that the join between two different metals is kept dry. Dissimilar Metals The best-known effect of …

Electrochemical Processes Explained

Electrochemical Processes

Electrochemical reaction, any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances—one a solid and the other a liquid. Electrolysis Pure water is a very poor conductor of electricity, but if a small amount of an acid, alkali …

Secondary Cell: Definition & Types

Secondary Cell: Definition & Types

Definition: A secondary cell can be recharged or restored. The chemical reaction that occurs on discharge may be reversed by forcing a current through the battery in the opposite direction. This charging current must be supplied from another source, which can be a generator or a power supply.  Figure 1 …

Primary Cell

primary cell types

Definition: A primary cell is a cell in which the chemical action cannot be reversed. A primary cell cannot be recharged. One might think that the chemical action of the zinc-carbon primary cell would continue to produce a voltage as long as the active ingredients of the cell were present. …

Continuous Trickle Charger Circuit Diagram

The purpose of a battery charger is to charge a battery without overcharging it. The simplest type of charge controller for renewable energy systems monitors the battery voltage and turns the charging current off or reduces it when the battery voltage exceeds a specified level. It turns the charging current …

Voltaic Cell Equivalent Circuit | Voltaic Cell Example

equivalent circuit of cell 2

Primary and Secondary Cells The simple voltaic cell is classified as a primary cell. Primary cells can supply current until the negative electrode is completely dissolved, the electrolyte is exhausted, or perhaps until polarization renders the cell useless. A secondary cell, on the other hand, can be recharged. That is, …

Voltaic Cell | Working and Construction of Voltaic Cell

Electrolyte Chemical Action

Voltaic Cell Definition A voltaic cell consists basically of two different metal plates immersed in an acid solution. The action of the acid removes electrons from one plate and accumulates them on the other plate. In this way, a potential difference is produced between the two plates, and a current …
