. Electronic apparatus for biological research. Electronic apparatus and appliances; Biology -- Research. COLD CATHODE DIODE Suppose we wish to design a stabilizer to supply 210 V at 0-70 mA. Then the load resistance which corresponds to maximum current is 210 V/70mA = 3,000 ohms. Suppose a string of stabilizers have been chosen which will strike at 255 V. Then 2 K, - F, = 510 - 210 = 300 V, and IR^ must be greater than this. Since Rj^ = 3,000 ohms, / must be 100 mA or greater. Let it be 10 per cent over the critical value, 110 mA, for safety. Taking 110 mA 2-3 ki2 510 volts Unstabilized.
