  • Abstract
    The author criticizes the existing methods for the measurement of radio frequency resistance and describes a new electrometer method, where a quadrant electrometer is put across the inductance in an oscillatory circuit. The condenser of this circuit is charged to the voltage V0and discharged thru the inductance by means of a special key. The throw of the electrometer will then be proportional to V02-L/2R. The theory of the method is given and it is shown how to eliminate the different possible sources of error. With this method the radio frequency resistance of even a very feebly damped circuit may be determined with an error well within one part in a thousand, and this determination may be made in a few seconds.
