Final answer:
In the context of an ideal OpAmp, V₊ is equal to V₋, signifying no voltage difference across the inputs due to infinite input impedance and gain.
Step-by-step explanation:
For an ideal Operational Amplifier (OpAmp), the condition V₊ = V₋ is assumed, where V₊ and V₋ are the voltages at the non-inverting (+) and inverting (-) terminals, respectively. This implies that there is no voltage difference across the input terminals when the OpAmp is operating under ideal conditions, which is due to the infinite input impedance and infinite open-loop gain of the ideal OpAmp. The provided formulas and calculations relate to calculating currents and voltages in various circuits, using Ohm's law and other electrical engineering principles to analyze the behavior of resistive circuits when subject to different voltages.
