  • Difference between SSD and HDD

    The Difference between SSD and HDD is given here. The solid hard disk or in its acronym SSD is a portable storage system that has been marketed to achieve a better public experience with the information that it seeks to…

  • Zener Diode: Symbol, Characteristics and Applications

    what is Zener Diode? A major application for Zener diodes is as a type of voltage regulator for providing stable reference voltages for use in power supplies, voltmeters, and other instruments. In this section, you will see how the Zener…

  • Wheatstone bridge formula Class 12

    The Wheatstone bridge circuit is widely used to precisely measure resistance. Also, the bridge is used in conjunction with transducers to measure physical quantities such as strain, temperature, and pressure. Transducers are devices that sense a change in a physical parameter…

  • Difference between Analog and digital signal

    There is a key difference between analog and digital signals. An analog signal is a signal generated by an electromagnetic phenomenon that can be represented by a continuous mathematical function with amplitude and period as a function of time, while…

  • Types of capacitors with applications

    “A capacitor is a device that can store charge.”Apart from resistors and inductors, it is the other basic component commonly used in electronic circuits. It is a device that has the ability to store charge which neither a resistor nor…

  • what is difference between impedence and reactance?

    Circuits with capacitors and inductors are more complicated than the resistive circuits we talked about earlier, in that their behavior depends on the frequency: A “voltage divider ” containing a capacitor or inductor will have a frequency dependent division ratio.…

  • What are the 7 different Types of logic gates?

    There are 7 types of logic gates which are: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. Logic gates are electronic circuits that make logical decisions. It has one output and one or more inputs. Output signal appears only…

  • Kirchhoff’s voltage and current law with examples

    What is Kirchhoff’s Voltage Law? Kirchhoff’s voltage law is a fundamental circuit law that states that the algebraic sum of all the voltages around a closed path is zero or, in other words, the sum of the voltage drops equals…

  • Operational Amplifier: Types & applications

    Early operational amplifiers (op-amps) were used primarily to perform mathematical operations such as addition, subtraction, integration, and differentiation—thus the term operational. These early devices were constructed with vacuum tubes and worked with high voltages. Today’s op-amps are linear integrated circuits (IC s) that  use…

  • Bipolar junction transistor(BJT):Applications & characteristics

    What is transistor? A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Or A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic…
