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.
Diagram of a zinc anode in a galvanic cell. Note how electrons move out of the cell, and the conventional current moves into it in the opposite direction. An anode is an electrode through which conventional current flows into a polarized electrical device. A common mnemonic is ACID for anode current into device. The direction of (positive) electric current is opposite to the direction of electron flow: (negatively charged) electrons flow out the anode to the outside circuit.
