Study of Variation of Total Thermal Radiation with Temperature with power supply and 2 dual range meters (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12266
Indian Lab Suppliers supplies the Study of Variation of Total Thermal Radiation with Temperature with power supply and 2 dual range meters (C.R.) (Product ID: 12266) as part of its electronics engineering lab equipment range. It verifies Stefan’s law by relating the power radiated by a tungsten filament to its temperature.
Quick Answer
A 6 V, 6 W tungsten filament bulb is driven from a built-in 0-6 V DC, 1 A IC-regulated supply with coarse and fine controls. A DC voltmeter (600 mV / 6 V) and DC ammeter (500 mA / 1 A), both switch-selectable, give the voltage and current at each setting. From V/I students find the filament resistance, and hence its temperature, while V × I gives the power radiated at equilibrium; a log-log plot of power against temperature should have a slope close to 4. The unit is self-contained. The bulb gets hot, so let it cool before handling.
