Description : Photoconductivity is a characteristic of semiconductors. When light falls on certain semiconductors, it (a) Sets free electrons from some of the atoms, increasing the conductivity (b) Ejects ... Establishes a potential difference creating a source of EMF (d) Produces heat raising the temperature
Last Answer : Photoconductivity is a characteristic of semiconductors. When light falls on certain semiconductors, it Sets free electrons from some of the atoms, increasing the conductivity
