Photoresistance refers to the property of certain substances to change their electrical conductivity under the influence of light. This phenomenon is also known as photoconductivity. A synonym for photoresistance is photoconduction. Other synonyms include optoresistance, light-dependent resistance, and light-sensitive resistance. These terms all describe the same basic concept: a material's ability to alter its resistance based on the amount of light it receives. Photoresistors, also known as light-dependent resistors, are commonly used in electronic circuits as light sensors or in applications that require precise light measurement. Understanding the various synonyms for photoresistance can help clarify technical discussions and expand scientific vocabulary.
