A nullator is defined as a circuit element where the voltage across the device and the current through the device are both zero. A series combination of a nullator and a resistor of value, R, will behave as a

1. resistor of value R.
2. nullator.
3. open circuit.
4. short circuit.

Correct answer: nullator.

Solution

A nullator inherently has both zero voltage and zero current, so when combined in series with a resistor, the entire circuit will still exhibit these nullator characteristics, effectively behaving as a nullator.
