DescriptionSTEP 1.6.2 Compensating the voltage drop by VNIC (practical circuit).png
English: The Ohm's voltage-controlled circuit is shown in this schematic and simulation. It consists of an input voltage source V, resistor R (real voltmeter with internal resistance R), an imperfect ammeter and an op-amp VNIC (voltage-inversion negative impedance converter). Simulate this circuit here.
