electrophorus; a device that produced static electricity. In 1776-77 he devoted his time to chemistry‚ studying atmospheric electricity‚ and devising experiments such as the ignition of gases by an electric spark in a closed vessel. In 1779 he became professor of physics at the University of Pavia‚ a chair he occupied for 25 years. By the 1800 he had developed the so-called voltaic pile‚ the first invention of the electric battery; it produced a steady stream of electricity. Volta also studied what we now

The company that I am working for has been expanding and thusly has more equipment and personnel. We traditionally use static IP addressing but this is no longer sufficient. It is now time that we start using DHCP due to the fact that this will allow better functionality through the automatic addressing and leasing of IP addresses. More benefits of using DHCP are the massive amount of IP addresses that are available in DHCP and the fact that DHCP will automatically recall an IP address once the lease

are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal or pelvic fins. An adult eel can reach any size from six to

Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are silver‚ gold

Chapter I I. Introduction Power electronics converters can be found wherever there is a need to change voltage‚ current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics‚ electrical currents‚ and voltage are used to carry information‚ where as with power electronics‚ they carry power electronics becomes the efficiency An inverter converts DC

EXAM 1 NOTES The actual pressure at a given position is called the absolute pressure‚ and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Most pressure-measuring devices‚ however‚ are calibrated to read zero in the atmosphere (Fig. 3–2)‚ and so they indicate the difference between the absolute pressure and the local atmospheric pressure. This difference is called the gage pressure. Pgage = Pabs - Patm The pressure at a point in a fluid has the same magnitude in all

Safety Rules Safety is defined as the state of being safe‚ while rule is a statement of what to do or not to do in a certain situation. Safety rules contain set of policies interpreting a law or policy to maintain safety. It is applicable in any area and must be done at all time. Unexpected situation like accident may occur in a workplace. That’s why safety rules come with its purpose‚ and it is to prevent the occurrence of any work related injury. Safety rules includes checklist of safety standards
