The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons is dependent on the frequency of the light that is incident on the metal''s surface.
Outputs from photocells, thermistors, and other transducers can be used to trigger UJTs, which in turn fire SCRs and triacs. UJTs are also used in oscillators, timers, and voltage-current sensing applications. Unijunction Transistor (UJT) Characteristic Curve. In normal operation, B1 is negative and a positive voltage is applied to B2.
Photocells are basically a resistor that changes its resistive value (in ohms Ω) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very innacurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch. The variations can be really
