A center-tapped full-wave rectifier is an electrical circuit used to convert alternating current (AC) into direct current (DC). It is commonly used in power supplies to ensure efficient DC voltage conversion.
A relay is an electrically operated switch that uses an electromagnet to mechanically operate a set of contacts. It is widely used in circuits to control a high-power or high-voltage circuit with a low-power signal, providing isolation between the control and load circuits.
A variable capacitor is an electrical component used to temporarily store electrical energy in an electric field. Unlike fixed capacitors, the capacitance of a variable capacitor can be altered by varying certain parameters such as the overlapping area of plates, the distance between them, or the dielectric material. They are widely used in applications like
Dielectric heating, also known as capacitive heating or radiofrequency (RF) heating, is a process in which non-conductive (dielectric) materials are heated by applying an alternating electric field. This heating occurs due to the molecular polarization of the dielectric material when subjected to a high-frequency AC electric field. It is widely used in industries such as
A function generator is an electronic device used to generate electrical waveforms over a wide range of frequencies. It is widely used in the fields of electronics, communications, and testing to create specific signals for testing, calibration, and experimentation. Figure 1: Block diagram of a function generator.
A toggle switch is a type of electrical switch that is operated by moving a lever or handle back and forth to open or close a circuit. Toggle switches are commonly used in various electronic devices and equipment to control electrical power or signal flow. They are reliable, easy to use, and versatile, making them
The batteries are available with some specific terminal voltages. e.g. 1.5V, 6 V, 12 V, 24 V, 48 V etc. If we want to have some terminal voltage other than these standard ones, then series or parallel combination of the batteries should be done. One more reason for connecting the batteries in series or parallel
