An electrician checks the amperage of a circuit with a multimeter.

Definition

1. Noun:
   • The strength of an electrical current measured in amperes: "Amperage" refers to the magnitude of an electric current, quantified using the unit of amperes (A). It is a measure of the rate of flow of electric charge.

Usage

• "Amperage" is a technical term used primarily in electrical engineering, electronics, and related fields.
• It is an uncountable noun. You typically refer to "the amperage" or "high/low amperage," not "an amperage."
• It is often discussed in relation to voltage and resistance, following Ohm's Law.

Examples

• Noun:
  • Check the amperage rating on the circuit breaker before connecting the new equipment.
  • A higher amperage is required to start the motor than to keep it running.
  • The device failed because it was subjected to an amperage beyond its specifications.

Advanced Usage

• "Amperage draw": The amount of current a device consumes from a power source.
  • The amplifier has a high amperage draw, so it needs a dedicated power line.
• "Amperage capacity": The maximum current a component or system can safely handle.
  • You must use a wire with sufficient amperage capacity for this application.

Variants and Related Words

• Ampere (A) (n): The SI base unit of electric current. One ampere is defined as one coulomb of charge passing a point per second.
  • The standard household outlet in many countries provides 15 or 20 amperes.
• Current (n): The general flow of electric charge. "Amperage" is the measurement of this current.
  • The current in the wire was too high, causing it to overheat.

Synonyms

• Current strength: The intensity of an electric current.
• Electrical current: The flow of electric charge (though this is the phenomenon itself, not the measurement of its strength).

Related Phrases

• "To measure amperage": To determine the strength of an electrical current.
  • You need a multimeter to measure the amperage accurately.
• "Amperage rating": The designated safe operating current level for a device or component.
  • Always check the amperage rating on a fuse before replacing it.
