Task 50336.
Absolutely black conductive thread glows in a vacuum current I1 = 1 A to a temperature T1 = 1000 K. Determine if a current strength I2 filament heated to a temperature of the T2 = 3000 K. The resistivity thread count beyond its temperature, power loss due to the thermal conductivity of suspensions thread and the return radiation neglected the surrounding bodies.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
