<p>The invention relates to a resistor assembly for dividing an applied voltage into an intermediate voltage being below the applied anode voltage in a cathode ray tube. The resistor assembly comprises an insulating substrate and a resistive voltage divider including a first and a second resistive layer provided on the insulating substrate, and an additional resistive network with a first network terminal and a second network terminal. The additional resistive network is coupled in series with the first resistive layer. Furthermore, the additional resistive network comprises first and second resistive portions which are releasably coupled to the network terminals via bridge connections. The bridge connections have a resistance which is substantially lower than the resistance of the resistive portions for adjusting a predetermined ratio of the resistive voltage divider. According to the invention, the first and second resistive portions have substantially different resistance values for selecting a predetermined resistance value from a range of possible resistance values of the additional resistive network for reducing the area of the resistor assembly occupied by the additional resistive network. This reduction allows a further reduction of the length of the resistor assembly.</p> |
