These capacitors are also known as plastic film, polymer film or film dielectric. Generally, these capacitors are also called film caps & power...
by Tarun Agarwal 7 years ago What is a Galvanometer : Working, Construction & Its Applications The Galvanometer development was done from the observation of a magnetic compass needle when it deflects close to an electrical wire. In 1820, a Danish physicist & chemist namely ‘Hans Christian Ørsted’ was discovered the first...
by Tarun Agarwal 7 years ago What is Bus Topology in Computer Networks & Its Differences There are various communication devices are connected to a network to establish a reliable communication network. The devices connected in a communication network are known as ‘nodes’. These nodes are connected through ‘Links’....
by Tarun Agarwal 7 years ago What is Circuit Switching – Diagram, Advantages & Disadvantages For transmission of data from sender to receiver, communication links are to be established. In a simple computer network, only one link connecting the sender and receiver would be sufficient. But for larger networks, there will exist more...
by Tarun Agarwal 7 years ago What is a Virtual Machine – Types and Advantages The concept of a virtual machine was introduced around 1960. It is the evolution of the time-sharing technique. In the time-sharing method, each program has full access to all the computer resources but at a time, only one program will...
