How is heat produced
Web21 nov. 2024 · X-ray production. To summarize, x-rays are produced in a standard way: by heating a filament, which releases electrons by thermionic emission, accelerating electrons with a high voltage and allowing them to collide with the focal spot on the target/anode. X-rays are produced via two interactions in the anode. Bremsstrahlung x-rays Web6 sep. 2016 · If H = V 2 R t ,then increasing resistance means decreasing the heat produced. Implies that the voltage V stays constant. So with V = I R if V stays constant and the resistance R increases then the current I decreases. A classic example of this happening is in a tungsten filament light bulb
