Examples of 'dark current' in a sentence
Meaning of "dark current"
In the context of electronics and semiconductors, dark current refers to the small electrical current that flows through a photosensitive device, such as a camera sensor, when it is not exposed to light. It is caused by thermal effects and leakage currents, and can lead to noise or undesired signal amplitude in the output

- The temperature-dependent current that flows in a photodetector when no light is shining on it.
