In this article, we will discuss the electrodynamometer wattmeter, its construction, advantages, and disadvantages. Let’s start with a basic introduction to the electrodynamometer wattmeter. An
The polarity test of the transformer is performed to determine the direction of induced voltages in the primary winding and the secondary winding. The polarity
This article describes the relationship between resistance and length of a material with the resistance wire formula. Resistance is the property of the material that
IP ratings classify the levels of protection against solid objects, dust, accidental contact, and water in electrical enclosures. IP ratings are key for understanding how
The slow movement of electrons in the conductor when an EMF is applied across the conductor is called Drift Velocity. The electrons do not move
Definition: An electric meter, also known as an electricity meter, electrical meter, energy meter, or kilowatt-hour meter, is used to measure the electrical energy consumed in a
In this article, we will study the theory and diagram of an autotransformer(or auto transformer). An auto transformer is a type of electrical transformer used
Residual magnetism refers to the remaining magnetization in a circuit after removing the external magnetic field. This article describes the residual magnetism and its types.
The dimensional formula of inductance is [ML2T−2A−2]. In this article, we will derive this dimensional formula of inductance. What is a Dimensional Formula? The dimensional
The inductance formula calculates the inductance of the inductor. This article describes the inductance formula and how to calculate inductance. When electric current flows through
