Every rancher gets the stones that have tumbled to his side and places them back on the divider yet being of uneven shapes and sizes‚ they don’t stay in their place and tumble off more than once. To such an extent‚ that the

Multiplier type Digital to Analog Converter (MDAC)‚ controlled by a microcontroller‚ serves as the other two arms. The microcontroller‚ after obtaining quadrature condition between the bridge output and one of the designated bridge voltages‚ acquires the current through and voltage across the series connected resistor. With these values and the value of digital input to the MDAC‚ the parameters of L or C or R values are evaluated by the microcontroller and displayed in appropriate display fields. The scheme

Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when
