Phasor diagrams are a graphical representation of the magnitude and directional relationship between two or more alternating quantities. In this article, we will learn about phasor and phasor diagram class 12. So let’s get started… What are phasors? A phasor…
In this short piece of the article, we are going to derive an expression for the RMS value of an alternating voltage, so let’s get started… Root mean square value of an alternating emf It is defined as that value…
In this short piece of article, we will derive an expression for the root mean square value of alternating current for a full cycle, so let’s get started… Root mean square (RMS) or virtual or effective value of AC It…
In this short piece of article, we will derive an expression for the average or mean value of AC for half cycle, so let’s get started… What is the average value of AC? It is defined as that value of…
In this article, we will discuss alternating current class 12, its amplitude, time period, and frequency, so let’s get started… What is an alternating current? Alternating current (AC) definition: An alternating current (AC) is an electric current that periodically reverses…
In this article, we will discuss the grouping of inductors i.e. inductors in series & parallel, class 12. So let’s get started… Grouping of inductors When two and more inductors are combined in an electrical circuit to give an equivalent…
In this article, we will derive an expression for the mutual inductance of two long coaxial solenoids. So let’s get started… What is mutual inductance? Mutual inductance is a phenomenon in which an emf is induced in the secondary coil…
Hmmm… Mutual inductance has more self-respect than self-inductance because it has a wide range of applications in electrical engineering. Mutual inductance is the main working principle of generators, motors, transformers, etc. Self-inductance induces an emf across the coil itself. But…
In this short piece of article, we will derive a formula for energy stored in the inductor. So let’s get started… Formula for energy stored in the inductor derivation Let’s take an inductor with some inductance, if anyone increases the…
In this short piece of article, we will obtain an expression of self-inductance of a long solenoid. So let’s get started… Expression for Self-inductance of a long solenoid Self-inductance of a long solenoid. Consider a long solenoid of length $l$…
