Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased…
Measurement of Capacitance using Schering Bridge: A very important bridge used for the precision measurement of capacitors and their insulating properties is the Schering Bridge Experiment. Schering Bridge basic circuit…
Bridge Controlled Error Detection: Bridge Controlled Error Detection - Whenever a bridge is unbalanced, a potential difference exists at its output terminal. The potential difference causes current to flow through…
Kelvins Bridge and Kelvins Double Bridge: When the resistance to be measured is of the order of magnitude of bridge contact and lead resistance, a modified form of Wheatstone's bridge,…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied…
pH Measurement Methods: pH is defined as the negative logarithm of the active hydrogen ion. It is a measure of the acidity or alkalinity of an aqueous solution. The pH…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In…
