Saptarshi Dutta (11DM-140) The General Electric Turnaround (1981-2000) Ranked at number 6 in the fortune 500 list‚ GE is the world’s most valuable and admired company. This status is attributed to the changes made by the company in the two decades from 1981 to 2000 under the leadership of CEO Jack Welch. In the 20 years that Jack led GE’s‚ revenues rose from $30 to $130 billion and company value went from $14 to $410 billion. Jack Welch’s entire strategy took place in 3 waves- First Wave (1981)

non-technological factor to shape electricity was the business- and competition-fueled "War of Currents" of the late 19th century between alternating and direct current AC and DC‚ respectively ("Electricity‚" 2006). During the initial years of electricity distribution‚ Thomas Edison ’s direct current was the standard for the United States‚ and Edison was not disposed to lose all his patent royalties. Direct current worked well for the incandescent lamps that were the principal load of the day. However

alternating current and direct current. Direct current (dc) comes from generators that do not change in polarity‚ always producing a positive charge. In alternating current (ac) the polarity of the terminals is always changing from positive to negative. Thus you are left with alternating current flow. There are different ways of measuring and generating alternating and direct current. Direct current only flows in one direction in a circuit. Because the polarity of a direct current voltage source

Rousselle Molina date submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field lines by looking at the experimental data

balance sheet consists of liabilities and assets. The concept of current assets includes the following: Investment in shares and advances to other firms and public companies not connected with the business of the borrowing firm are excluded from current assets. The dead inventory i.e. slow moving or obsolete items should not be classified as current assets; The amount representing inter company transactions has to be treated as current only after examining the nature of the transactions and the merits

CHAPTER - 13 MAGNETIC EFFECTS OF ELECTRIC CURRENT 1) Magnetic field and Field lines:- a) Magnetic field :- The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. b) Magnetic field lines:- Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move. The magnetic field lines around

produced? Have you ever noticed how your hair stands straight and stiff when you comb it vigorously on a dry‚ cold day? Or how difficult it is to remove dust particles from your comb? Your hair and the comb become charged by rubbing. This stationary electric charge is described as static electricity. Activity 1. Rub a plastic sheet with flannel and then hold the plastic sheet near Styrofoam bits. What do you observe? From the observations made‚ you can conclude that rubbing produces static electricity

Investigating the current - potential difference relationship for a metal wire. Aim: To design an experiment that will facilitate an I - V Graph to be ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in

usual equation for measuring electric current flowing through a series is I = V/R. The current flowing in a series is affected by the voltage and the resistor that is also creating the series. Electric current is a flow of electric charge through a conductive medium. These charge is in a form of moving electrons in a wire. The SI unit for electric current is ampere (A) and can be measured by using a device called ammeter. Change in temperature can change the current carrying capacity of a conductors
