The function of a non-polarized capacitor is to provide capacitance without a specific polarity requirement. Unlike polarized capacitors, which must be connected with the correct polarity (positive and negative terminals), non-polarized capacitors can be connected in either direction in a circuit. This versatility makes non-polarized capacitors suitable for AC (alternating current) circuits and applications where … Read more
The armature in an electric motor serves a critical role in converting electrical energy into mechanical energy through electromagnetic interactions. It is a core component of the motor’s rotor, where it consists of windings or conductors that carry current. When electrical current flows through the armature windings, it generates a magnetic field. This magnetic field … Read more
In vehicles, alternators play a crucial role in converting AC (alternating current) generated by the rotational motion of the engine into DC (direct current) for charging the vehicle’s battery and powering the electrical systems. Here’s how AC is converted into DC in the alternators of vehicles: AC Generation: Alternators produce AC through the principle of … Read more
Varistors, specifically Metal Oxide Varistors (MOVs), are used in circuits primarily for transient voltage suppression and overvoltage protection. They are designed to protect electronic devices and circuits from voltage spikes, surges, and transient disturbances that can occur due to lightning strikes, switching events, or other electrical anomalies. Varistors exhibit a high resistance under normal operating … Read more
Electromagnetic induction and inertia share similarities in their fundamental principles and effects. Inertia refers to an object’s resistance to changes in its state of motion, whether at rest or in motion. Similarly, electromagnetic induction involves the generation of an electromotive force (EMF) in a conductor when it moves through a magnetic field or when there … Read more
Whats an operational amplifier and how does it work ? An operational amplifier, often abbreviated as op-amp, is a versatile electronic component widely used in analog circuits for amplification, signal conditioning, filtering, and mathematical operations such as addition, subtraction, integration, and differentiation. It consists of multiple transistors, resistors, and other components integrated into a single … Read more
Radio telescopes collect data from celestial objects and phenomena by detecting radio waves emitted or reflected by these sources. The process begins with the radio waves traveling through space until they reach the Earth’s atmosphere. Radio telescopes are equipped with large parabolic dishes or arrays of antennas that are sensitive to radio frequencies. When the … Read more
The breakdown in a Zener diode occurs due to a process called Zener breakdown or avalanche breakdown. This phenomenon happens when the reverse bias voltage applied across the Zener diode exceeds its breakdown voltage (also known as the Zener voltage). Under normal operation in the reverse bias region, a small reverse current flows due to … Read more
What is the difference between rectifier and converter ? A rectifier and a converter serve distinct purposes in electrical systems, each with specific functionalities and applications: Difference between Rectifier and Converter: A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). It typically uses diodes to rectify AC input by … Read more
