Power transformers and Distribution transformers are extensively used in power systems for stepping up and down the voltage level for various applications such as transmission and distribution. Read through this article to find out the major differences between power transformers and distribution transformers and how they function.What is a Transformer?A Transformer is a static electrical machine which changes the level of voltage and current in a circuit without changing the frequency of the supply. Transformers works on the principle of electromagnetic induction.Based on the design, operation, purpose of use, transformers are classified into different types such as auto-transformer, current transformer, ...

Both conductors and insulators are extensively used in various fields of electrical and electronics engineering. In this article, we will compare and contrast the various features of conductors and insulators and how they function.What is a Conductor?The material which allows the electric current to pass through it is known as conductor. In other words, the material which has less than 4 electrons in its outermost shell is known as conductor.When electric potential is applied across a conductor, the electrons can freely move from atom to atom. In a conductor, the valance band and the conduction band are overlapped each other. ... Read More
LED lamps consume less energy as compared to Halogen lamps. LED lamps are cost efficient too. Read through this article to find out the major differnces between LEDs and Halogen lamps and how they function.What is LED Lamp?An electric lamp which produces light by using light emitting diodes or LEDs is known as an LED lamp or LED light bulb. An LED lamp works on the principle of electroluminescence, i.e. it emits the light due to the interaction of an electric field with a suitable solid.Basically, an LED is a specially doped PN junction diode which is made of special ...

Both analog and digital circuits are extensively used in various fields of electrical and electronics engineering for signal processing. Go through this article to find out how analog and digital circuits function and how they differ from each other.What is an Analog Circuit?An analog circuit is a type electronic circuit that can process any analog signal or data and produce an output in analog form. Analog circuits are composed of resistors, inductors and capacitors, etc.The type of signal which is a continuous function of time is known as an analog signal. All the real-world signals are the analog signals, therefore, ... Read More
Series and Parallel electric circuits are heavily used in various applications such as resistive series circuits, voltage divider circuits, home appliances, etc. It is important to have a good knowledge of how these circuits work. Go through this article to get an overview of how Series and Parallel circuits operate and how they differ from each other.What is an Electric Circuit?An electrical network which has closed path for electric current to flow is known as electric circuit or circuit. An electric circuit consists various circuit elements such as energy sources, resistors, inductors, capacitors, etc. An electric circuit must have at ... Read More
Both thyristors and transistors are semiconductor devices widely used in various applications. Read through this article to find out how a thyristor differs from a transistor.What is a Thyristor?A thyristor is a four-layer three-terminal semiconductor device. A thyristor consists of three PN-junctions. The three terminals of the thyristor are: anode (A), cathode (C) and gate (G). The gate is the terminal of the thyristor which is used to provide control signal to the device. The circuit symbol of the thyristor is shown in Figure-1.A thyristor possesses high ratings of voltage and current and also has the ability to handle large ... Read More
