Wien Bridge Circuit Diagram: The Wien Bridge Circuit Diagram shown in Fig. 11.27 has a series RC combination in one arm and a parallel combination in the adjoining arm. Wien's bridge in its basic form,…
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 arrangement is given in Fig.…
Hays Bridge Circuit: Hays Bridge Circuit, shown in Fig. 11.23, differs from Maxwell's bridge by having a resistance R1 in series with a standard capacitor C1 instead of a parallel. For large phase angles, R1 needs…
Maxwell Bridge Theory: Maxwell Bridge theory, shown in Fig. 11.21, measures an unknown inductance in terms of a known capacitor. The use of standard arm offers the advantage of compactness and easy shielding. The capacitor…
Comparison Bridge: There are two types of Comparison Bridge, Namely Capacitance Comparison Bridge Inductance Comparison Bridge 1. Capacitance Comparison Bridge: Figure 11.18 shows the circuit of a capacitance comparison bridge. The ratio arms R1, R2…
Block Diagram of Wheatstones Bridge with Digital Readout: The tremendous increase in the use of digital circuitry has had a marked effect on electronic test instruments. The early use of digital circuits in bridges was…
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 the detector (say, a galvanometer)…
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, the Kelvins Bridge is employed.…
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 to two opposite junctions and…
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 scale runs from 0 -…
