TEXT: The authors give the theory of volt-age multipliero and divi-
ders designed around raetal resistors, consider the orid6e method of
multiplication and division, and analyze its ervors, The bridge me-
thod is based on the fact that wheii a metal wire R is inserted in
one of the bridge arms and heated by applying a voltage U of one
frequency, while the bridge supply voltage U has a difl"erent fre-
Z> 2
quency, then the det-ector volta5e TJD is pro~,ortional to the product
