For non-ohmic devices, the graph between V and I is
Correct answer: A. Not a straight line
- A. Not a straight line
- B. A straight line
- C. A curve
- D. All of above
Explanation
For non-ohmic devices, the graph between voltage (V) and current (I) is not a straight line. Instead, it typically exhibits non-linear behavior, such as curves or other non-linear shapes, indicating that the resistance of the device changes with variations in voltage or current.

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.
