wheatstone's bridgeI assume you are referring to AC & DC Wheatstonebridges
Wheatstone's bridge
Cycloconverter is a ac to low frequency ac converter.which convert ac to low freq.ac with help of scr.
the principle of wheatstone bridge is,there is a potential fall is directly proportional to the length of the wire, and this fall is also equalt to the fall accross the resistances applied in parallel to the battery. It is a form of wheatstone bridge.
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
You rectify AC voltage through a diode bridge to convert it to DC.
Total cost to make a bridge rectifier is about Σ25. A bridge rectifier is an electrical device that converts alternating currents (AC) to direct current (DC). The process of bridge rectification is a simple one using four diodes, two AC and two DC wires, an AC source and pliers.
DC Bridge... We use DC supply, Detector is also a DC current detector and we use only resistive components no need for wegner's earthing device balancing time is comparatively less.. where as in AC bridges opposite of above. i.e. AC supply, AC current detector resisitive+ reactive componants need for wagner's earthing device and balancing time is high as we use AC supply..
The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
Ac x 1.4 -1.4=dc
How to test a diode bridge ? Diode bridge is a device is used to convert an AC signals (say AC voltage) to DC output (say DC voltage). So, to test it, you can apply a AC voltage v = Vm Sin (wt) at its 2 inputs and measure DC output voltage Vdc.
The basic principle of a cantilever bridge is that the bridge is supported entirely at one end, the rest being held in place by steel pillars or beams.
