What is the purpose of spark plugs in an engine ?
Spark plugs play a crucial role in the internal combustion process of an engine. Their primary purpose is to ignite the air-fuel mixture in the combustion chamber, initiating the combustion…
How is motion converted into electric energy ?
Converting motion into electric energy involves utilizing the principles of electromagnetic induction, where the relative motion between a conductor and a magnetic field induces an electromotive force (EMF) or voltage….
How is RC circuit a low pass filter and CR circuit a high pass filter ?
The RC circuit, consisting of a resistor (R) and capacitor (C), acts as a low-pass filter, allowing low-frequency signals to pass through while attenuating high-frequency signals. On the other hand,…
What makes the tiny speakers in mobile phones and tablets so loud ?
The tiny speakers in mobile phones and tablets are remarkable examples of compact and efficient audio technology. Despite their small size, these speakers can produce relatively loud and clear sound….
What is the self resonant frequency of a capacitor ?
The self-resonant frequency (SRF) of a capacitor is a frequency at which the capacitive reactance and the inductive reactance within the capacitor become equal. At this resonant frequency, the capacitor…
What is the basic principle of a diesel generator ?
A diesel generator operates based on the fundamental principles of internal combustion engines and electromagnetic induction. The basic principle involves converting the chemical energy stored in diesel fuel into mechanical…
How does an induction motor work as a generator ?
Induction motors can operate as generators through a phenomenon known as regenerative braking or regenerative power conversion. The basic principle behind this process lies in the transformation of mechanical energy…
How to connect 3 phase motors in star and delta connection ?
Connecting three-phase motors in star (wye) and delta configurations involves specific wiring arrangements that determine how the motor windings are connected. Both configurations have their advantages and use cases. Here’s…
What is the difference between a switch and a diode ?
Switches and diodes are both electronic components, but they serve different functions in electronic circuits. Here’s a detailed explanation of the differences between a switch and a diode: Switch: Function:…
What is the reason for using reactor in capacitor bank ?
The use of a reactor in a capacitor bank is a common practice in power systems and electrical networks. Reactors, also known as inductors or chokes, are employed for various…
