Inductors produce back EMF because of Faraday’s law of electromagnetic induction. When the current flowing through an inductor change, it induces a voltage in the opposite direction, resisting the change in current. This is known as back electromotive force (back EMF), which opposes the initial change in current. Here areContinue Reading

What is reverse breakdown voltage? The reverse breakdown voltage of a diode is the voltage at which the diode transitions from its normal, off-state behavior to a state of breakdown, allowing a significant reverse current to flow. In this breakdown region, the diode loses its insulating properties and behaves moreContinue Reading

Diodes are semiconductor devices that allow current to flow in one direction while blocking it in the opposite direction. They are typically made using materials such as silicon or germanium. While it is possible to create diodes using other semiconductor materials, carbon presents certain challenges that make it unsuitable forContinue Reading

Super capacitors, also known as ultracapacitors or electric double-layer capacitors (EDLCs), offer high capacitance and rapid energy storage and release capabilities. However, they tend to be more expensive compared to traditional electrolytic capacitors or other energy storage devices like batteries. These factors is the reason to the higher cost ofContinue Reading

When the voltage across a capacitor exceeds its rated voltage, several factors come into play that can lead to its failure, which might even include explosions. These key factors contribute to the potential failure of the capacitor. Dielectric Breakdown Internal Arcing Gas Production How it happens? The dielectric material insideContinue Reading

Resistors have a tolerance because of manufacturing variations. Resistor tolerance helps maintain consistent circuit performance despite inherent deviations in resistance values. This allows for an allowable range of deviation from the specified resistance value to ensure accurate functionality. Manufacturing Variations Resistors are produced in vast quantities, and manufacturing processes canContinue Reading

When selecting a resistors for a specific application, engineers need to consider several key characteristics to ensure proper functionality and reliability. Here are the key factors to consider when selecting a resistor type, Resistance Value Resistor value should match circuit requirements. The most accurate value can be chosen using availableContinue Reading

These metals are utilized in different resistor types and compositions to achieve desired resistance values, power ratings, and other characteristics. Carbon (C): Carbon Composition, Carbon Film Nickel-Chromium (NiCr): Nichrome Wirewound Tin (Sn): Tin Film Nickel (Ni): Nickel Thin Film Chromium (Cr): Chromium Film Tantalum (Ta): Tantalum Film Copper (Cu): CopperContinue Reading

Large resistors, often referred to as power resistors or high-wattage resistors, are used in electronics and various applications for several reasons. However, the main reason is to dissipate more power without damaging the resistor. Why? More power dissipate through a resistor, the more heat it generates. so large resistors areContinue Reading
