Why is a capacitor used in a fan ?
Capacitors are commonly used in fans to facilitate the starting and running of the electric motor, especially in single-phase induction motors commonly found in household appliances like fans. Here’s a…
Why cant we make a transistor by using two diodes back to back ?
While it might seem intuitive to connect two diodes back to back to create a transistor-like structure, this arrangement does not function as a transistor. Transistors are three-terminal devices with…
Why we use AC fuses in DC circuits ?
The use of AC fuses in DC circuits is not recommended due to the inherent differences between alternating current (AC) and direct current (DC) systems. Fuses are protective devices designed…
How can transistors be used to store information ?
Transistors can be used to store information in various ways, and one of the common applications is in the construction of digital memory elements such as flip-flops and registers. The…
Why the transistor is grounded ?
In electronic circuits, grounding the transistor serves various purposes related to the stability and proper functioning of the circuit. Grounding helps establish a common reference point for voltages in the…
Which is better OLED or AMOLED ?
OLED (Organic Light Emitting Diode) and AMOLED (Active Matrix Organic Light Emitting Diode) are display technologies that share similarities but also have distinct differences. The choice between OLED and AMOLED…
Why does Tesla Motors prefer battery packs over supercapacitors ?
Tesla Motors, like many electric vehicle manufacturers, prefers battery packs over supercapacitors for several reasons, primarily related to energy density, cost, and overall performance characteristics. While supercapacitors have unique advantages,…
Why are Zener diodes heavily doped ?
Zener Diodes and Doping: 1. Introduction to Zener Diodes: Purpose: Zener diodes are special types of diodes designed to operate in the reverse breakdown region. They are employed for voltage…
How does a filtering capacitor smooth a changing current ?
A filtering capacitor is a crucial component in electronic circuits designed to smooth or filter a changing current, especially in power supply applications. Its ability to mitigate variations in the…
