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…
Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
Transistor Tester and its characteristics: The term Transistor Tester (or analyser) used in this text is for instruments giving quantative measurements of transistor parameters. The tester should be able to…
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…
LCR Bridge: Basic LCR Bridge (Skeleton Type) : A simple bridge for the measurement of resistance, capacitance and inductance may be constructed with four resistance decades in one arm, and…
