A current-voltage curve, or I-V curve, is a graphical representation showing the relationship between the electric current through and the voltage across an electrical component or device. It is fundamental in characterizing the performance of components like diodes, transistors, and solar cells, helping to reveal their operating regions and efficiency.

Performance of components

Diodes are semiconductor devices that allow current to flow in one direction only, functioning as a one-way valve for electric current. They are essential components in converting alternating current (AC) to direct current (DC) and are used in various applications such as rectifiers, voltage regulators, and signal demodulators.
