Abstract
The value of dielectric constant of paraffin wax doped with different concentrations of lamp black carbon decreases with the increase in the concentration of lamp black carbon in it. It is a case of loss of dielectric property and gain in conducting property and the specimen behaves as a random binary mixture of conductors and insulators, more specifically, a random network of resistors and capacitors. Anderson Bridge is used to investigate the magnetic permeability and susceptibility of different media inside a solenoid. The resistive property of manganin wire is studied using Kelvin double Bridge.
