What are circuits that obey Ohm's law referred to as?

• A. Reactive circuits
• B. Series circuits
• C. Ohmic circuits
• D. Nonlinear circuits

Answer: (C)

Circuits that obey Ohm's law show a direct, proportional relationship between voltage and current, with a constant resistance. In these circuits, V = IR holds, so increasing voltage yields a proportional increase in current. This behavior defines Ohmic circuits. If the resistance changes with voltage or current, the V–I relationship becomes nonlinear, and the circuit is not Ohmic. Reactive components like capacitors and inductors also don’t follow a simple V ∝ I relationship in AC conditions, because they involve reactance and phase differences rather than a constant resistance. The way components are connected (series or not) doesn’t by itself determine Ohmic behavior. So the circuits that obey Ohm's law are Ohmic circuits.
