 Current-voltage characteristic

A current-voltage characteristic describes the relation between terminal electric potential difference and electric current for specified physical conditions. A resistor obeying Ohm's law gives a straight line; a diode has an asymmetric relation.

The current-voltage (I-V) characteristic is a fundamental relationship in electronic devices that describes how the current flowing through a device varies with the applied voltage across it. This characteristic is crucial for understanding the behavior of various electronic components such as diodes, transistors, resistors, and more.
