A technician checks the amp reading on a multimeter.

Definition
  1. Noun:
    • A unit of electric current: An "amp" is the base unit of electric current in the International System of Units (SI), formally called an ampere. It measures the flow of electric charge.
    • A nucleotide in biochemistry: In a biochemical context, "amp" is an abbreviation for adenosine monophosphate, a nucleotide that serves as a fundamental component in cellular energy metabolism.
Usage Examples
  • Noun (Electric Current):
    • This device draws a current of 10 amps.
    • A standard household outlet is usually rated for 15 or 20 amps.
  • Noun (Biochemistry):
    • AMP is a crucial molecule in the transfer of cellular energy.
    • The enzyme catalyzes the conversion of ATP to ADP and AMP.
Advanced Usage
  • Technical Specification: Used to specify the capacity or draw of electrical devices, circuits, and fuses.
    • The circuit breaker is rated for 30 amps to prevent overload.
  • Scientific Context: Used in research and academic writing in biology and chemistry.
    • Cyclic AMP (cAMP) acts as a secondary messenger in many biological processes.
Variants and Related Words
  • Ampere (n): The full, formal name for the unit of electric current.
    • One ampere is defined as one coulomb of charge passing per second.
  • Amplifier (n): An electronic device that increases the power of a signal. Often informally shortened to "amp" in music contexts (e.g., guitar amp). This is a distinct, related word.
  • Adenosine Monophosphate (n): The full name for the biochemical compound AMP.
  • Milliamp (n): One thousandth of an ampere, a common subunit.
    • The sensor operates on a current of just a few milliamps.
Synonyms
  • Ampere: The formal synonym for the unit of current.
  • Adenylate: A less common synonym for adenosine monophosphate in biochemistry.
Related Phrases
  • Amp hour (Ah): A unit of electric charge, representing the charge transferred by a steady current of one ampere flowing for one hour.
    • The battery has a capacity of 50 amp hours.
  • Volt-amp (VA): A unit used for apparent power in alternating current circuits.
