The I-V Graph for a non-Ohmic material is always
Correct answer: A. Curved
- A. Curved
- B. Horizontal
- C. Linear
- D. Perpendicular
Explanation
The I-V graph of non-ohmic materials is characterized by a curved shape rather than a straight line, indicating a non-linear relationship between current and voltage.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
