CHAPTER 1 Overview of Current Account Balance * Introduction: The current account is the difference between exports of goods and services and imports of goods and services. If we denote the current account balance by CA‚ we can express this definition in symbol as CA = EX – IM The current account balance is one of two major measures of the nature of a country’s foreign trade (the other being the net capital outflow. A current account surplus increases a country’s net foreign assets by the

ELECTRICITY (CLASS – X) QUESTIONS FOR PRACTICE 1. State the law that governs the strength of the current passing through a metallic conductor when a p.d is applied across its end. Illustrate this law graphically? 2. Why is an ammeter connected in series and voltmeter in parallel in a circuit? 3. In an experiment the current flowing through a resistor and potential difference across it are measured. The values are given below. Show that these values confirm Ohm’s Law and also find the resistance

is proportional to the current (I)‚ where the constant of proportionality is the resistance (R). Series and parallel resistors - The total resistance of resistors connected in series is the sum of their individual resistance values. The total resistance of resistors connected in parallel is the reciprocal of the sum of the reciprocals of the individual resistors. Power dissipation - where V (volts) is the voltage across the resistor and I (amps) is the current flowing through it. Using

Electrical resistance Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current. The SI unit of electrical resistance is the ohm. (“Electrical Resistance” http://en.wikipedia.org/wiki/Electrical_resistance) Electrical resistance is the measure of the degree that a substance against to the electric current through it in an electric circuit. Good conductors are associated with low resistance and poor conductors are associated with high resistance

other side of the lemon. The nail and penny must not touch. This is a single cell of a battery. The zinc nail and the copper penny are called electrodes. The lemon juice is called electrolyte. All batteries have a "+" and "-" terminal. Electric current is a flow of atomic particles called electrons. Certain materials ‚ called conductors‚ allow electrons to flow through them. Most metals (copper‚ iron) are good conductors of electricity. Electrons will flow from the "-" electrode of a battery

Jill Ridgley General Electric Strategic Planning During the 1980s General Electric’s Chairman‚ Jack Welch‚ became highly influential and equally controversial in the world of strategic management. Although Welch focused on gaining competitive advantage for his organization‚ he also began downsizing and restructuring GE. GE’s strategic planning and operational efforts began a shift toward Total Quality Management and improving productivity. (WriteWork contributors. “Levels of Planning in Management”
