Answer the following question given this paragraph: 

An ammeter measures the current traveling through the circuit. They are designed to be connected to the circuit in series, and have an extremely low resistance. If an ammeter were connected in parallel, all of the current would go through the ammeter and very little through any other resistor. As such, it is necessary for the ammeter to be connected in series with the resistors. This allows the ammeter to accurately measure the current flow without causing any disruptions. In the circuit sketched above, the ammeter is .


Q: An ammeter must be connected in series with what to allow it to accurately measure the current flow without causing any disruptions?


A:
resistors
