Leading Manufacturer, Supplier & Retailer of LDR PHOTO TRANSISTOR.
| The presented board is designed to study of opto - devicessuch as photo conductive cell ( light dependend resistor), photo transistor, photo diode (pin diode), and photo voltic cell electrical (V - I) characteristics.The light source is 12V21W tungston filament lamp, powered by variableregulated dc supply ( 0 - 10V, 2Amp). One regulated dc supply upto 19voltwith two dual range digital panel meters. There is a 3 way selector, used toselect the meters interconnections to take readings of lamp voltage, dc supplyvoltage and current and photo cell voltage and current. |
