Difference between Diode and Transistor
Both diodes and transistors are types of semiconductor devices that find a wide range of applications in different electronic circuits such as clippers, clampers, oscillators, rectifiers and amplifiers, etc. Go through this article to get an overview of how diodes and transistors function and how they are different from each other.What is a Diode?A diode is a semiconductor switching device which is constructed by combining two layers of N-type and P-type semiconductor materials. For this reason, a diode is also called as PN junction diode. The circuit symbol of the diode is shown in Figure-1.A diode has only one PN-junction ...
Read MoreDifference between Multimeter and Voltmeter
Multimeter and Voltmeter are handheld measuring devices. Voltmeters are used when one needs to measure only voltage. Multimeters, in contrast, can be used to measure multiple electrical quantities such as current, voltage, resistance, etc.Go through this article to find out the features of multimeters and voltmeters and how they differ from each other.What is a Multimeter?Multimeter, as the name implies, is a combination of different measuring instruments in a single unit. It can measure several electrical quantities such as current, voltage, resistance, etc. An extended version of multimeter can also measure other electrical properties like transistors gain, diode forward voltage, ...

Bipolar Junction Transistor (BJT) and Insulated Gate Bipolar Transistor (IGBT) are two types of transistors that are used in electronic circuits to control the currents. Read through this article to get an overview of how BJTs and IGBTs function and the major differences between them.What is BJT?BJT stands for Bipolar Junction Transistor. The BJT is a three layer, three terminal semiconductor device which is used in the electronic circuit for switching and amplification of signalsA BJT is formed by sandwiching either a P-type or N-type material between two layers of N-type material or P-type material respectively. Thus, based on the ...
Read MoreDifference between Power Transformer and Distribution Transformer
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, ...
Read MoreDifference between Conductors and Insulators
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 MoreDifference between LED and Halogen
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 ...
