To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. Remember, electric current is measured in amperes, or amps for short.

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 ...
