This book offers a revolutionary perspective on the variations of electrical resistances in different atmospheric conditions, particularly humidity levels. Unlike previous understanding, the author reveals that these variations are not inherent to the Manganin wire used in the resistances, but rather due to moisture absorption by the shellac coating, which expands the wire and increases its resistance. This discovery challenges long-held assumptions and sheds new light on the reliability of Manganin resistance standards, especially in settings with fluctuating humidity. Moreover, the author presents practical solutions to mitigate these variations, such as sealing the coils with paraffin or placing them in sealed cases, providing valuable insights for professionals working with electrical systems and precision measurements. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
