rotating anode. focal track made of tungsten -rhenium which spins on the copper anode rotor and has molybdenum backing because these metals conducts it draws the heat away from the anode. - because the anode is rotating the electrons dont hit at the same spot everytime so the anode does not over heat. focal spot.
The anode is not always the positive lead. It is the electrode through which electric current flows into a polarized electrical device. For a discharging battery, this is the negative lead. This is how I connected anode/anion and cathode/cation during chemistry class when we were discussing batteries. I was confused when I learned that for other components, such as an LED, the kathode is negative, and the anode is positive.
