Types of Capacitor Nowadays in today’s world of electrical and electronics, there are various types of capacitor are available. And each of these capacitors has its own characteristics and uses. These capacitors are broadly classified into two types, One is on the basis of their work and the second on the basis of the dielectric … Read more
What is a Capacitor? Complete Explanation about Capacitor Capacitor Definition A Capacitor is defined as a passive element that is designed to store electrical energy in the form electric field established by the two polarities of charges on the two electrodes of a capacitor. A capacitor consists of two conducting parallel plates which are separated … Read more
AC and DC current Let’s start with the introduction of the new article “AC and DC current. Most of the countries in the world including India use an ac current system for the generation of electrical power. Talking about the dc supply system, it has its own importance and basic necessity for electronic devices, … Read more
What is a Galvanometer? Let’s start with the introduction of the New article “What is a galvanometer”. A galvanometer is a permanent magnet moving coil (PMMC) instrument that is designed to detect and measure the small value of current and voltage in an electrical circuit. This type of instrument is very sensitive to enormously low … Read more
What is a Star to Delta starter? Star to Delta starter or star-delta starter is one of the most common methods used for starting of three-phase induction motor. When the stator winding of the motor is directly connected with the supply, it will draw a very high current, and to control this high current Star-Delta … Read more
Hysteresis Loss and Magnetization curve MAGNETISATION CURVE OR B-H CURVE The curve drawn giving the relationship between magnetic flux density (B) and the magnetizing force (H)is known as the magnetization curve or B-H curve. When a magnetizing force is applied on a magnetic material, then the magnetizing flux density ‘B’ increases in direct proportion and … Read more
What is Relay? A relay is a device that opens and closes an auxiliary circuit under predetermined conditions in the main circuit. Relays are extensively used in electrical, electronics engineering, and many other fields. There are relays that are sensitive to conditions of current, voltage, temperature, frequency, or some other combination of these conditions. … Read more
Single Phase Induction Motor A single-phase induction motor in its physical appearance is similar to a three-phase squirrel cage induction motor. The 1-Φ phase induction motor has a distributed single-phase winding while in the case of the 3-Φ induction motor the stator has distributed three-phase windings. On comparing the performance characteristics of the single-phase induction … Read more
WHAT IS SEMICONDUCTOR? A semiconductor is defined as a substance whose electrical conductivity is intermediate between metallic conductors and non-metallic insulators. In other words, we can also define semiconductor as the substance which has resistivity (10-4 to 0.5 Ωm) in between metallic conductors and non-metallic insulators. Examples of semiconductors are germanium, silicon, selenium, etc. Properties … Read more
MAXIMUM POWER TRANSFER THEOREM The Maximum Power Transfer theorem is one of the useful methods in circuit analysis to find the value of load resistance when there would be the maximum transfer of power from the source to load. Statement of Maximum Power Transfer Theorem According to this theorem, a resistive load that is being … Read more
