first part of this book will examine alternative powered circuits, circuits
which display diverse combinations of resistance, inductance and capacity.The
second part will examine the momentum of charged particles in both electric and
In this book, the author give an account of some recent electrical
researches, experimental as well as theoretical, in the hope that it may assist
students to gain some acquaintance with the recent progress of Electricity and
yet retain Maxwell's Treatise as the source from which they learn the great
principles of the science.
