Final answer:
An ammeter is not a device that measures potential. Instead, it is used to measure the rate of flow of electric current in a circuit by being connected in series with the circuit component being measured.
Step-by-step explanation:
An ammeter is not a device that measures potential. Rather, an ammeter is an instrument used to measure the rate of flow of electric current in a circuit.
To measure current, the ammeter must be connected in series with the circuit component being measured. This means that the ammeter is placed in the path of the current, and all of the current in the circuit flows through the meter.
Therefore, the statement that an ammeter measures potential is False.
