Self Testing in Embedded Systems
The implementation of some self-testing capabilities in an embedded design is worthwhile unless available memory is completely exhausted. Although modern electronics are amazingly reliable, they are still susceptible to failure.
Electrolytic Capacitor – Types, Construction, Polarity and Leakage Current
Electrolytic capacitors are one of the most commonly used types of capacitor. Their capacitance values range from about 1 μF to 6800 μF. Electrolytic capacitors are more popular because the
What is an Electrical Fuse? Types, Properties, and Application
An Electrical Fuse is a vital component of any equipment. It is used as an indicator of a defect in the system. It protects the equipment from overcurrent or overloading.
