WebJul 5, 2024 · When you connect a meter to a circuit and use it to measure current, all of the current in the circuit flows through the meter. It is also a measurement for which you need to reconfigure the meter—you have to … WebSep 12, 2024 · Measuring Current with an Ammeter. To measure the current through a device or component, the ammeter is placed in series with the device or component. A series connection is used because objects in series have the same current passing through them. (See Figure \(\PageIndex{2}\), where the ammeter is represented by the symbol A.)
