[Class 38 (iv)] [Also in Group XL] The effects of unwanted capacity introduced by circuit elements e.g. a battery or other source of potential, such as a rectifier, are reduced by series resistances 9, 10 bridged by an alternating current path 11 and building out means are provided which together with the inherent capacity and the added resistances produce a complex circuit which simulates substantially a pure constant resistance. Fig. 2 shows the application to the voltage supply for the collecting electrode 1 of a cathode ray tube of the double-sided mosaic type, Fig. 1, feeding a load 4 in which an inductance 12 is provided equal to CR2 where C is the inherent capacity and R is the load resistance while the added inductance 12 is shunted by a resistance 13. In a modification, Fig. 3 (not shown), the resistance is arranged in shunt to the load resistance in series with the added inductance.
