Appointments: 1. Acquire data for voltage-current characteristics for distances: cm between photocell and light source. Make measurements with different voltages. 2. Acquire data for illumination characteristics for voltages 5 15 35 V and calculate the sensitivity of photocell as a function of applied voltage. Make measurements at 12 different distances. 10 cm 50 cm 3. Sketch graphs for obtained characteristics and explain processes taking place in photocell. Calculate errors for voltage, current and distance measurements. Used measuring devices and set-up: Nr.. Title Precision class Measuring diapason The value of smallest scale Imm 1. Ruler 0-100cm 2.
