Electronics guide: Diode, Capacitor, Arduino Platform, and Electronics Store
A condenser, more commonly known as a capacitor in modern terminology, serves several important functions in electric circuits. One primary function is to store electrical energy temporarily in the form of an electric field between its two conductive plates separated by a dielectric material. This stored energy can be released quickly when needed, making capacitors … Read more
Transistors can act as switches by controlling the flow of current between the collector and emitter terminals based on the voltage applied to the base terminal. In a bipolar junction transistor (BJT), for example, when a small current is applied to the base terminal, it allows a larger current to flow from the collector to … Read more
Generators typically start through a process involving an external mechanism such as an electric starter motor or a manual crank. In the case of small portable generators, an electric starter motor is often used, which is powered by a battery. When the start button or key is activated, the starter motor engages with the engine’s … Read more
Storing large amounts of AC current directly is impractical because AC (Alternating Current) changes direction periodically, which complicates direct storage. However, electrical energy in the form of AC can be converted into other forms for storage. One common method is to convert AC to DC (Direct Current) using rectifiers or inverters and then store the … Read more
Using big capacitors instead of batteries poses several challenges primarily due to differences in energy storage and discharge characteristics between capacitors and batteries. Capacitors are designed to store and release electrical energy rapidly but typically have much lower energy densities compared to batteries. This means capacitors can store less energy per unit volume or weight … Read more
Selecting the best condenser microphone for a female voice depends on various factors such as voice tone, singing style, and the environment where it will be used. Some popular choices among condenser microphones known for their clarity and warmth suitable for female voices include the Neumann U87, AKG C414, and the Audio-Technica AT4050. These microphones … Read more
Flux in a transformer is generated through the principle of electromagnetic induction. When an alternating current (AC) flows through the primary winding of a transformer, it creates a varying magnetic field around the winding. According to Faraday’s Law of Electromagnetic Induction, this changing magnetic field induces a voltage in the secondary winding. This induced voltage … Read more
The inductance of an inductor refers to its ability to store energy in a magnetic field when an electric current flows through it. It is a property that quantifies how much magnetic flux (φ) is induced per unit of current (I). Mathematically, inductance (L) is defined as L = Φ / I, where Φ is … Read more
Damaging or spoiling a Zener diode can occur through several methods, with excessive current being one of the most common causes. Zener diodes are designed to operate in the reverse breakdown region, where they maintain a stable voltage across their terminals. Applying a current that exceeds the maximum rated current (Izmax) can lead to thermal … Read more
Some light bulbs, particularly certain types of fluorescent bulbs or LEDs, may continue to glow faintly even after they have been switched off. This phenomenon occurs due to residual electrical charge or capacitance in the circuit. When the switch is turned off, the flow of current to the bulb stops, but there can still be … Read more
