The ammeter was first invented by German scientist Johann Christian Poggendorff in 1820. He developed the device to measure electric current flowing through a conductor.

How do you connect an ammeter and voltmeter?

To connect an ammeter, you must place it in series with the circuit so that the current flows through the ammeter. To connect a voltmeter, you must place it in parallel with the component you are measuring the voltage across. Make sure to set the ammeter and voltmeter to the proper range before connecting them.


Why is ammeter connected in series with the load?

An ammeter is connected in series with the load to measure the current flowing through the load. By placing the ammeter in series, it becomes a part of the circuit path so that all the current flowing through the load also passes through the ammeter, allowing for an accurate measurement of the current.


What is the least count of ammeter?

The least count of an ammeter refers to the smallest change in current that can be measured by the device. It is typically determined by the scale divisions on the display of the ammeter. For example, if an ammeter has a least count of 0.1 A, it means that it can detect changes in current as small as 0.1 ampere.


Which of these is used to measure current in series circuits?

An ammeter is used to measure current in series circuits. It is connected in series with the circuit components to measure the flow of electric current through them.


What will an ammeter show if the circuit is broken?

Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
