The long-term viability of Bitcoin is in jeopardy. The announcement by Google that it has built a quantum computer, which can quickly hack bitcoin and the encryption on which the internet relies, and which can do mathematical tasks that are mathematically impossible, was the impetus for this. However, recent research claims that quantum supremacy won't change Bitcoin in any way. However, what exactly sets Bitcoin apart from quantum supremacy? Let’s try and find that out in this difference-based article. What is Quantum Supremacy? The term, “Quantum Supremacy” is a reference to the fact that quantum computers, which are fueled by ...

An electronic circuit consisting of diodes and capacitors and converts an AC electrical signal from a lower voltage value to a higher DC voltage value is referred to as a voltage multiplier. Voltage multipliers are used in several electronic appliances to generate a voltage signal of few volts to millions of volts. In this article, we will discuss the definition, circuit, types, operation, and applications of the voltage multiplier. What is a Voltage Multiplier? A voltage multiplier is an electronic circuit consisting of capacitors and diodes and is used to multiply or rise the voltage level of an AC signal. ... Read More
In an electric circuit, when two or more electric circuit components are joined together in such a way that there is only one path for the flow of electric current, such connection of circuit components is referred to as series circuits. Therefore, in a series circuit, the current through all the circuit component remains the same, but the voltage across each element is different. In this article, we will discuss about the voltage in series circuits and how to calculate it. What is Voltage in Series Circuits? In a series circuit, the voltage across each element is different and depends ... Read More
Prioritizing a marketing plan is a necessary component of running a company. Any number of marketing strategies can be used by a company, but the one chosen must align with the company's goals and be feasible given the company's structure and resources. Business owners and managers might seek advice from business strategists when deciding between a market focus, product focus, production focus, or sales focus. This should only be done once a thorough understanding of the components of each marketing strategy and the likely responses of the target audience has been attained. The two concepts share a lot of similarities, ... Read More
An electronic circuit in which the output voltage follows the input voltage is known as a voltage follower. In other words, a voltage follower is an electronic circuit whose output voltage remains the same as the input voltage. We can design a voltage follower using an operational amplifier. A voltage follower implemented using an operational amplifier is commonly known as a Unity Gain Operational Amplifier or Op-amp Buffer. In this article, we will discuss the definition, circuit, working, advantages, and applications of a voltage follower designed using an operational amplifier. So let’s begin with the basic introduction of a voltage ... Read More
In this article, we will discuss the uninterruptible power supply (UPS), its block diagram, types, and applications. So, lets’ begin with the basic definition of the uninterrupted power supply (UPS). What is a UPS? UPS stands for Uninterruptible Power Supply. An Uninterruptible Power Supply (UPS) is an electrical device used to provide emergency electrical power to different electrical loads in the case of a main power supply failure. A UPS or uninterruptible power supply uses batteries and supercapacitors to store electrical energy and delivers this stored electrical energy when the main input power supply fails. However, a typical UPS battery ... Read More
A voltage regulator is an electronic circuit which is used to control the variations in the output voltage of a power supply so that it will remain within the suitable limits. Since, in the case of practical circuits, the voltage changes due to several reasons such as change in input voltage, change in temperature of the circuit components, etc. But, ideally, the voltage output of the power supply should be in a certain range that is acceptable for the connected circuit. This is achieved by using a circuit called voltage regulator. In this article, we will discuss the different types ... Read More
The electrical and electronic components such as resistors, capacitors, inductors, wires, cables, insulators, etc. are made up of different types of material. We generally refer all these materials as engineering materials. Based on electrical resistivity, the engineering materials are categorized into three categories namely – conductors, semiconductors, and insulators. Since every material present in the nature possess a finite amount of electrical resistance. Also, this resistance can change with the variation in the temperature. The following points briefly explain the variation in resistance of the different types of materials with the change in temperature − The resistance of conductors ... Read More
A parameter of an oscillatory system, such as an ac circuit, which expresses the relationship between stored energy and energy dissipation is known as quality factor of the system. The quality factor is also called as Q-factor. Mathematically, the quality factor or Q-factor of an ac circuit is given by the ratio of the maximum electrical energy stored in the circuit to the energy dissipated in one time period, i.e., $$\mathrm{ Q \: Factor =\frac{2\pi \times maximum\: energy \: stored\: per\: cycle}{Energy\: dissipated\: per\: cycle} } $$ The quality factor (Q-factor) can ...

In electrical and electronic circuits, some components are used to supply the required electrical energy for the operation of the circuit. These components are known as energy sources. Energy sources are the active circuit elements that can supply the necessary excitation, i.e. required electrical energy, to the circuit. In practice, we have several types of voltage and current sources such as batteries, generators, alternators, photovoltaic cells, etc. In this article, we will discuss the different types of energy sources. Types of Energy Sources The energy sources are broadly classified into the following two types − Voltage Sources Current Sources ... Read More
