Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits, the current is the same through each component. The potential ...

Ammeter needles will sometimes dance disconcertingly as a result. A potential problem with ammeters is they are live all the time and – in the case of some vehicles – are not circuit-protected ...

Some types of ammeter have a pointer on a dial, but most have a digital display. To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it.

Additionally, it discusses the use of sensitive equipment to measure very small currents and illustrates the randomness of charge flow in electric circuits. Keywords electric current, ammeter ...
