amperemeter

An electrician uses an amperemeter to check the current in a circuit.

Definition

1. Noun:
   • Instrument for measuring electric current: An "amperemeter" is a device used to measure the flow of electric current in a circuit, typically expressed in amperes (amps). It is often connected in series with the circuit to obtain an accurate reading.

Usage Examples

• Noun:
  • The technician connected an amperemeter to the circuit to check the current. (The device measured the electric flow.)
  • An amperemeter must be placed in series with the load to function correctly. (The instrument requires a specific connection method.)

Advanced Usage

• "to read an amperemeter": to observe and interpret the measurement displayed on the device.

  • He read the amperemeter and noted that the current was 5 amps. (He recorded the value shown on the instrument.)

• "amperemeter scale": the calibrated markings on the device that indicate current values.

  • The amperemeter scale was marked from 0 to 10 amperes. (The range of measurement was clearly indicated.)

Variants and Related Words

• Ammeter (n): a common synonym for amperemeter; a device for measuring electric current.

  • The ammeter showed a sudden spike in current. (The instrument indicated an increase.)

• Amperage (n): the strength of an electric current expressed in amperes.

  • The circuit's amperage was too high for the equipment. (The current measurement was excessive.)

Synonyms

• Ammeter: a device specifically for measuring current; often used interchangeably with amperemeter.
• Current meter: a general term for any instrument that measures electric current.
