A _ is also known as a _ (_) or _, is an electronic component that exhibits a change in electrical resistance in response to the intensity of incident light.

This belongs to the class of optoelectronic devices and is widely used for light sensing and control applications.

Photoresistors are typically made of a _ material, such as cadmium sulfide (CdS) or lead sulfide (PbS), which has _ properties.

When exposed to light, the _ in the incident light interact with the semiconductor material, causing the _ or _ of _ (electrons or holes) within the material. This interaction alters the _ of the semiconductor and, consequently, its _.

The pin configuration of a photoresistor depends on its _ and _.

In most cases, a photoresistor has two pins, typically labeled as "_" and "_" or "_" and "_" for short.

These are used to establish electrical connections with the external circuit.

The "_" pin is the positive terminal, and the "_" pin is the negative terminal.

Pins are usually spaced _ and can be inserted into a breadboard or soldered onto a PCB for _.

When integrating a photoresistor into a circuit, the _ pin is connected to the positive voltage supply or input, while the _ pin is connected to the ground or negative side of the circuit. The _ developed across the photoresistor due to changes in _ is then measure or utilized in the circuit for _ or _.
