Calculation of the current in non-linear surge-current-generator circuits

Surge-current generators are used to test non-linear resistors and surge diverters. Although the circuit is basically very simple, it is possible to calculate the surge current only by numerical solutions of the differential equation for particular values of the parameters. The paper gives the results of such calculations made at Manchester University on the differential analyser and the electronic computer. The application of the results to certain practical problems is discussed.
