FAQ:

Q: How do you connect an ammeter in a circuit?

A: Ammeters are always connected in series in the circuit to measure current. If your circuit is just a battery and a resister then you need to open the circuit, connect the ammeter in series and then close the circuit.

Q: What is the difference in an ammeter and a multimeter?

A: As nouns the difference between ammeter and multimeter is that ammeter is a device that measures the magnitude of an electric current, especially one calibrated in amperes while multimeter is an electronic measuring instrument that combines multiple functions; a combined voltmeter, ammeter and ohmmeter. Other Comparisons: What’s the difference?

Q: What are the advantages of ammeter?

A: It is strong,portable. It does not dependent on the earth’s magnetic field. It could be made very accurate. An ammeter is used to measure the magnitude of electric current in an electric circuit. Some ammeter has no hysteresis error. It is used both AC and Dc measurements.

Q: How is ammeter and voltmeter connected in a circuit and why?

A: There is a difference between the ways in which, a voltmeter and an ammeter are connected in a circuit. When measuring the voltage across a resistor or a conductor element, the voltmeter is always connected in parallel. As opposed to this, to measure the current flowing through a circuit element, an ammeter should be connected in series.
