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,…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz,…
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…
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…
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.…
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…
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.…
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…
