name the component used in electric circuits that is sensitive to light. give the full name, not the abbreviation.

The component used in electric circuits that is sensitive to light is called a "Photoresistor." Its full name is "Light Dependent Resistor." This component changes its resistance according to the intensity of light falling on it, with resistance decreasing as light increases. It is widely used in light detection circuits, light-activated switches, and other applications where sensitivity to light is needed.
