Both the PN junction diode and the Zener diode are semiconductor devices that are extensively used in various electronic circuits. A PN junction diode is mainly used for rectification (transforming AC into DC), while a Zener diode is used for voltage regulation in the electronic circuits.There are a number of ... Read More

A magnet is a material or object which has ability to produce a magnetic field and can attract or repel other ferromagnetic materials. Based on the method of production of magnetic field, the magnets are classified into two types viz. −Permanent magnetElectromagnetThe main difference between an electromagnet and a permanent ...

Voltage and current are the two fundamental electrical quantities. The voltage is the factor in an electric circuit which causes electric current to flow in the circuit. The magnitude of the voltage and current depend upon each other. However, there are several differences between voltage and current which are described ... Read More

Welding and soldering are widely used in the fabrication industry. Both welding and soldering are used for joining metallic parts by the application of heat. In this article, we will compare welding and soldering by considering various factors like metaling temperature, heat source, use of flux, deformation, etc. But, before ... Read More

The electric power supply we use in our day-to-day life is of AC or alternating current power supply. The alternating current or AC supply is the type of electric power supply in which the magnitude of the electric current changes continuously with time and the direction changes periodically. Almost 90% ... Read More

The interruption in the supply of electricity has increased drastically over the years due to increased demand and it influenced the electricity industry. To overcome the problem of irregularities in the electricity supply, two of the most common technologies viz. generator and inverter of electric power supply are used. The ... Read More

EMF and Voltage are the two fundamental aspects of electrical and electronics engineering. They may appear as same, but they are different electrical quantities. In order to understand the difference between EMF and voltage, we first need to understand their meaning.What is EMF?EMF stands for Electromotive Force. The measure of ... Read More

Both conduction and convection are modes of heat transfer from one system to another. When there is a difference in the temperature of two systems, then the transfer of heat takes place from the system of higher temperature to the system of lower temperature.In practice, this transfer of heat takes ...
