Voltage Rating of Capacitors

Engineeering Projects
electrolytic capacitor

What is  Voltage Rating of Capacitors? Voltage rating of capacitors :Capacitor are designed and manufactured to operate at a certain maximum voltage. This maximum voltage can be regard as working voltage (WV). A Capacitor (in other words Condenser) is a passive electrical device that can store electrical energy by accumulating electrons on its metallic surface separate by a finite distance filled with dielectric material like air, Bakelite etc. within the space between metallic surfaces. Nowadays, capacitor is an essential components of each and every circuit that are deign today. Neither…

Call Indicator Using MC68HC705J1A Microcontroller circuit

Intercoms and calling bells fit properly only in the luxurious hotels, lodges and high class buildings. In small vicinity like small hotels, offices and clinics, these are not the correct options to choose for communication between the working/assisting staffs and people. It is all because of the cost and the fact that this provision can be made for limited number of points and other alternatives are chosen over it i.e. call indication systems. In early days, such call indications systems employed multiple distinct paths/cables to connect each call point to…
