Abstract :
The ideal a.c. bridge would include a variable conductance standard, but no such component can be made for high frequencies. The need for it can be avoided by working with a slightly unbalanced bridge, in which the unbalanced signal is a measure of the conductance of the specimen. The method is particularly suitable for measurements of dielectric loss, using micrometer-controlled electrodes. There is no restriction on the frequencies which can be used; examples are given of measurements at 0.1 and 30 MHz.
