Question

Information about Ammeter.​

Answer 1

Answer:

Explanation:

An ammeter is a measuring instrument used to measure the current in a circuit. Electric currents are measured in Amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.

Answer 2

• An ammeter  is a measuring device that is used to determine the current in a circuit.
• Amperes (A) are the unit of measurement for electric currents.
• In most cases, the ammeter is connected in series with the circuit that will be used to measure the current.
• The resistance of an ammeter is typically low enough that it does not produce a large voltage drop in the circuit being monitored.
• Milliammeters and microammeters are instruments that are used to measure tiny currents in the milliampere and microampere range.
• The first ammeters were laboratory gadgets that operated using the Earth's magnetic field.
• Improved instruments that could be put in any position and provided precise measurements in electric power systems were developed by the late nineteenth century.
• In a circuit, it's usually symbolized by the letter 'A.'
