Final answer:
An ohmmeter with an external resistance that is double the resistance of the device will result in an open circuit.
Step-by-step explanation:
In an ohmmeter, connecting the two terminals with an external resistance that is double the resistance of the device results in an open circuit. An open circuit is a path in which no current flows, because the circuit is incomplete. This means that there is no complete path for the current to flow between the terminals of the ohmmeter.
