This lab comprises of phase shifting transformers, reactive load and various other equipments used for calibration and measurement of electrical quantities. This laboratory is
equipped with all electrical bridge circuits like Kelvin's Double Bridge,Maxwell’s bridge, Schering Bridge to facilitate the measurement of unknown values of elements like resistor,
capacitor and inductor. Errors in electrical measuring instruments can also be found. We can also find real and reactive power of unbalanced loads. Also through this lab students will
be enlightened to learn PSPICE software package for building and simulating the circuits. The same can be used in industries for PCB designing.
