DEFINITION

Classification: 320/FOR.168

Foreign art collection in which means are provided for short-circuiting the impedance, in whole or in part, by conducting means of negligible resistance which operate to short circuit the entire impedance in one step, or parts of the impedance in one or more major steps, i.e., without passing through intermediate and infinitesimal values of said impedance.
