To determine which graph correctly represents the relationship between potential difference (voltage) and current in a non-ohmic resistor, we need to understand that non-ohmic resistors do not follow Ohm's law. Instead, their resistance changes with voltage or current.
In a non-ohmic resistor, the graph of current (I) versus voltage (V) is typically nonlinear. Here are the characteristics to look for:
- A straight line through the origin indicates an ohmic resistor (constant resistance).
- A curve that shows increasing current with increasing voltage suggests a non-ohmic behavior, where the resistance decreases as voltage increases (e.g., a filament bulb or diode).
Without seeing the specific graphs (A, B, C, D), you would look for the one that shows a nonlinear relationship—typically a curve rather than a straight line.
If you have the graphs available, please describe them or provide their general shapes, and I can help identify which one represents a non-ohmic resistor!
