The sensitivity of the d. c. device operating in unstable regime of pa depends on the parameter sc which is the ratio of currents flowing
through the feeding electrodes. The parameter sc plays the role of "an amplifier" so that in the neighborhood of the critical point the
layers with different resistance values are expressed by anomalies of large amplitudes.
