Open Circuit Voltage: What is it?

What is Open Circuit Voltage? When an open circuit condition is created in any device or circuit, the difference of electric potential between the two terminals is known as the open-circuit voltage. In network analysis, the open-circuit voltage is also known as the Thevenin Voltage . The open-circui

Eddy Current Testing

A non-destructive test technique that may be used on conductive materials is eddy current testing. Adjacent to the test surface is a test coil that is powered by alternating current. Eddy currents are created in the test piece as a result of the alternating magnetic field which is produced. The test

What is Ohm’s Law?

Ohm’s Law – Statement: Ohm’s law states that the current flow through a conductor is directly proportional to the voltage across the conductor and inversely proportional to the resistance of the conductor, where the temperature remains constant. Where, I denotes Current, V denotes Voltage and R deno

What is Watts Law? Explain relationship among Ohm’s & Watt’s law

What is Watts Law? The relationship in an electrical circuit between amperage, voltage drop, and power is 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 pow

Kirchhoff’s Current Law

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 com

Faraday’s Laws of Electromagnetic Induction

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 electro

Statement, Formula, Uses, and Limits of Coulomb’s Law

Coulomb’s Law: Coulomb’s law states that the force of attraction or repulsion between two charges is 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 r

Explain Lenz’s Law

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

DC Voltage: What is it?

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 volt

Electrical Polarity: What is it?

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 t

Independent Voltage and Current Sources

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 electrica
