|Abstract:||The details of an electronic instrument, viz. bipolar logarithmic amplifier that can efficiently measure point discharge currents associated with positive and negative potential gradients are described. The device uses a reversely biased double diode (6H6) valve for the measurement of point discharge currents and potential gradients are calculated using standard formulae. Currents in the range 10-9 10-5A for both the polarities can be measured with this device which, hence, can be used during both fair weather and disturbed conditions in the atmosphere.|
