What is Watts Law?The relationship in an electrical circuit between amperage, voltage drop, and poweris described by Watts law. According to Watts Law, the product of an electrical circuit’s voltage and current determines the power of the system.Energy is transferred at a rate called electric power. The unit of power measuredisjoules per second (J/s).When one joule of work is performed each second, one watt of electricity is lost each second (W).Formula for Watts Law:Watts law can be expressed u

Kirchhoff’s Laws include two fundamental principles in electrical circuit analysis: Kirchhoff’s Current Law (KCL) (Kirchhoff’s First Law or Kirchhoff’s 1st Law)& Kirchhoff’s Voltage Law (KVL) (Kirchhoff’s Second Law or Kirchhoff’s 2nd Law).These principles serve as essential tools for evaluating complicated electrical circuits, allowing engineers &researchers to predict &comprehend the behavior of circuits in various configurations. Kirchhoff’s Laws are widely applied in Electronics

Faraday’s law, also known as Faraday’s law of electromagnetic induction, is a fundamental law of electromagnetism that predicts how a magnetic field interacts with an electric circuit to produce an electromotive force (EMF). This is referred to as “electromagnetic induction.”Faraday laws of electromagnetic induction:Faraday’s Laws of Electromagnetic Induction consist of two laws:1. The first law describes the induction of emf in a conductor and2. The second law calculates the conductor’s generat

Coulomb’s Law:Coulomb’s law states that the force of attraction or repulsion between two chargesis directly proportional to the product of their charges and inversely proportional to the square of their distance from one another. It functions on the section that connects the two charges that are regarded of as point charges.Coulomb’s Law Formula:Where,F= Electric Force,K= Coulomb’s Constant,q1, q2= chargesr= between distanceWhat Is one Coulomb of Charge?It is known as a coulomb when two charges

What is Lenz’s Law?Lenz’s law of electromagnetic induction explains that the direction of the current induced in a conductor by a changing magnetic field (as per Faraday’s law of electromagnetic induction) is such that the magnetic field created by the induced current opposes the changing magnetic field that caused it. The direction of thecurrent flow is shown byFleming’s right-hand rule.Lenz’s law is based on Faraday’s law of induction, which says that a changing magnetic field will cause a cur

What is DC Voltage?DC voltage stands for “Direct Current Voltage”. While this sounds confusing, the term “DC” has become used more broadly to refer to a system that has constant polarity. Hence DC voltage is a voltage that produces or would produce a DC current. Conversely, an AC voltage is a voltage that produces or would produce AC current.DC in this context refers more broadly to quantities that don’t regularly change polarity or that have zero (or effectively zero) frequency. AC refers to qu

Now consider an AC circuit with two voltage sources. Here, magnitude, polarity, and phase angle are used to find the equivalent voltage. Electrical Polarity in AC Voltages In the first figure, both sources have the same polarity. Hence, the equivalent voltage is the addition of both. But these are the polar form—First, we need to convert this polar form into a rectangular form. And it will be—Now, the equivalent voltage is the addition of each of the X-components and Y-components (i.e. )—Ag

A voltage source is a device that provides a constant or varying electric potential difference between its terminals. A current source is a device that provides a constant or varying electric current through its terminals. Both voltage and current sources are essential for powering various electrical circuits and devices.However, not all sources are the same. Depending on how they behave and interact with other circuit elements, sources can be classified into two main categories: independent and

What is the Temperature Coefficient of Resistance?The temperature coefficient of resistancemeasures changes in the electrical resistance of any substance per degree of temperature change.Let us take a conductor having a resistance of R0 at 0oC and Rt at toC, respectively.From the equation of resistance variation with temperature, we getThis αo is called the temperature coefficient of resistance of that substance at 0oC.From the above equation, it is clear that the change in electrical resistance
