Kirchhoff’s Law Kirchhoff’s current law (KCL) imposes constraints on the currents in the branches that are attached to each node of a circuit. In simplest terms‚ KCL states that the sum of the currents that are entering a given node must equal the sum of the currents that are leaving the node. Thus‚ the set of currents in branches attached to a given node can be partitioned into two groups whose orientation is away from (into) the node. The two groups must contain the same net current. In general

The history of telecommunication began with the use of smoke signals and drums in Africa‚ the Americas and parts of Asia. In the 1790s‚ the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunicationsystems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication

Background of the Study Electricity plays very important role in the lives of people to make their work become easier and faster. It also provides productivity to our community. Industries use it to run motors efficiently. Several years ago‚ REINA which composed of 3 municipalities is simply a single town‚ which is Infanta. There was no supply of electric current in the town. Some public and private sector uses generator and some devices that generate electricity for the operation of different

Kleinrock was born into a Jewish family in Manhattan on June 13 1934. Kleinrock’s interest in electrical engineering began at the age of 6 while reading a superman comic book. When the young engineer reached the centerfold he stumbled upon a paper showing him how to build a crystal radio. Struck with awe and curiosity he began t gather the material

SHOCK HAZARD! TO PREVENT THE POSSIBILITY OF SEVERE PERSONAL INJURY‚ DEATH‚ OR EQUIPMENT DAMAGE DUE TO ELECTRICAL SHOCK‚ ALWAYS BE SURE THE POWER SUPPLY TO THE APPLIANCE IS DISCONNECTED BEFORE DOING ANY WORK ON THE APPLIANCE. THIS CAN NORMALLY BE ACCOMPLISHED BY SWITCHING THE BREAKER FOR THE AIR CONDITIONER TO OFF‚ DISCONNECTING ALL EXTERNAL ELECTRICAL CONNECTIONS AND CORDS‚ SWITCHING ON BOARD ELECTRICAL GENERATORS AND INVERTERS TO OFF‚ AND REMOVING THE CABLE FROM EACH POSITIVE TERMINAL ON ALL STORAGE

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is
