Abstract :
A semigraphical method of solving for harmonics in the input current to a network containing a number of linear and nonlinear resistances in any combination, when a sinusoidal voltage is applied across the network, is presented herewith. The treatment is restricted to nonlinear resistances in which the d-c volt-ampere characteristic is the same regardless of the direction of current. While the method has the errors inherent in any graphical solution, the results indicate good accuracy with little labor.
