A "cathode ray tube" (CRT), as shown in the image at right and the diagram below, is an evacuated glass tube. A current runs through a filament at the right end of the tube. When the metal filament gets very hot, electrons occasionally escape from it. These electrons can be accelerated away from the filament by Coil applying a potential difference AVacc across the metal plates labelled A and B in the diagram. Accelerating plates The electrons pass through a hole in plate B and enter the glass sphere. There they pass between the two horizontal metal "deflection" plates labelled C and D. A potential difference AVdef can be applied across these plates, to deflect the beam of electrons. Coil In front of and in back of the glass sphere are two coils, through which current Deflection plates can be run to produce a magnetic field in the region between the deflection plates. The coils are oriented so they both produce magnetic fields into the page in this region. AV sce 米 a Oj out of the page…

R3 4. In a parallel circuit, there is more than one loop or pathway so charge flow gets split up or recombined at junction points. Therefore current is not the same at every point in the circuit. Fill out the table for the circuit diagrammed at the right.
