Pronunciation: [ˈə͡ʊmɐmˌiːtə] (IPA) 
The spelling of the word "ohmammeter" is based on its phonetic transcription. In IPA, the word is transcribed as /oʊ.mæ.mə.tər/. The first syllable "oh" represents the long "o" sound, while the second syllable "mam" uses the "æ" sound. The third syllable "meter" uses the "ə" sound and emphasizes the last syllable as the stress falls on it. Thus, the spelling of "ohmammeter" is based on the sounds made when speaking the word.
Ohmammeter is a specialized measuring instrument used mainly in the field of electrical engineering and electronics to measure the electrical resistance or impedance of a circuit component or device. It is primarily designed to measure unknown resistance values, such as resistors, coils, or conductors.
The ohmammeter combines the principles of an ohmmeter and an ammeter to provide accurate and precise resistance measurements. It consists of a calibrated analog or digital meter, which displays the resistance value in ohms, and two test leads that are connected to the component being measured.
To use an ohmammeter, the test leads are connected to the terminals of the component or device, and the instrument applies a known voltage across the test leads. The resulting current flowing through the component is then measured and used to calculate the resistance value based on Ohm's Law (R = V/I), where R is the resistance, V is the voltage, and I is the current.
Ohmammeters are widely used in various applications such as troubleshooting electrical circuits, testing the integrity of electrical connections, and determining the quality and performance of electronic components. They are essential tools for professionals in fields like electronic repair, electrical installations, and circuit design, where accurate resistance measurements are crucial for maintaining safety and ensuring proper functionality.
A combined ohmmeter and ammeter.
A practical medical dictionary. By Stedman, Thomas Lathrop. Published 1920.
The word "ohmammeter" is a combination of two terms: "ohm" and "ammeter". The etymology of these individual words is as follows:
1. Ohm: The term "ohm" is derived from the surname of Georg Simon Ohm, a German physicist who is recognized for formulating Ohm's law. Ohm's law states that the electrical current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. It was published in 1827, and in honor of his contribution, the unit of electrical resistance, "ohm", was named after him.
2. Ammeter: The word "ammeter" is a combination of "amper(e)" and "meter".
