The phrase "electric jar" is spelled using the phonetic sounds /ɪˈlɛktrɪk dʒɑːr/. The word "electric" is written with the short "i" sound, followed by a hard "k" and a soft "c". The ending "-ic" is pronounced with emphasis on the second syllable. "Jar" is spelled with the "j" sound and the "a" vowel, followed by a liquid "r". This term refers to a type of storage device used to hold electrical energy, commonly known as a capacitor.
Electric jar refers to a device that is utilized to store and discharge electrical energy. It typically consists of two conducting plates, often made of metal or another conductive material, separated by an insulating material known as a dielectric. The conducting plates may take the form of curved or cylindrical surfaces, or they could be flat and parallel. The dielectric material could be solid, liquid, or gaseous, depending on the specific design and purpose of the electric jar.
The electric jar operates on the principle of capacitance, which is the ability of a system to store an electric charge. When a potential difference, also known as a voltage, is applied across the conducting plates, an electric field is established within the dielectric material. This electric field causes a separation of charge, with positive charge accumulating on one plate and negative charge on the other. The result is the storage of electrical energy within the electric jar.
Electric jars have diverse applications, ranging from energy storage in electronic devices and power grids to the generation and control of high voltages in various scientific and industrial settings. They are often used in capacitors and high-voltage capacitors. The design and materials used in an electric jar can vary greatly depending on its intended purpose, and advancements in technology continue to drive innovations in their construction and efficiency.
A jar so prepared as to be capable of being charged with electricity.

The word "electric jar" does not have an established etymology. However, it can be understood as a combination of two separate elements:
1. "Electric": The term "electric" is derived from the Latin word "elektrum", meaning amber. The ancient Greeks discovered that when amber was rubbed with certain materials, it emitted an effect similar to static electricity. The Greek word "ēlektron" evolved into the Latin "electricus", and eventually, the English term "electric" was formed.
2. "Jar": The term "jar" is derived from the Old French word "jarre", which originally referred to a large earthenware vessel for holding liquids. The word has since evolved to encompass various meanings, including containers of different materials and shapes.
