What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.

------------------------------------------------- OBJECT ORIENTED PROGRAMMING Q.What is the difference between Constructor and Function or Method? Constructor will be automatically invoked when an object is created whereas method has to be called explicitly. Constructor needs to have the same name as that of the class whereas functions need not be the same. * There is no return type given in a constructor signature (header). The value is this object itself so there is no need to indicate a

Ty Cormier Gemini Electronics 1. What was the business model of Gemini? The business model was to produce TV’s on a just-in-time basis to pass on most of the distribution savings to the consumers. He planned to cater to the big box retailers such as Best Buy and Walmart to name a few‚ who wanted to cut down their supply chains by sourcing TV’s in North America. By shortening the supply chain you increase reliability making it easier to address uncertainties as well as building lean production

The Effectiveness of Acceptances Communicated by Electronic Means‚ or — Does the Postal Acceptance Rule Apply to Email? Eliza Mik* The ‘traditional’ classification into ‘instantaneous’ and ‘non-instantaneous’ methods of communication must be abandoned. As all Internet transmissions are instantaneous‚ the choice between the principle of receipt and the postal exception must be based on other criteria. The focus must be shifted from communication devices to the characteristics of the communication

Basic Estimation Techniques In order to implement the various techniques discussed in this class‚ the students must be able to determine the mathematical relation between the economic variables that make up the various functions used in economicsdemand functions‚ production functions‚ cost functions‚ and others. For example‚ a manager often must determine the total cost of producing various levels of output. As you will see later‚ the relation between total cost (C) and quantity

However‚ the main drawback to induction is the short range. The receiver should be close to the transmitter or induction unit to inductively couple with it. Resonant inductive coupling has implications for solving the two problems associated with non-resonant inductive coupling and electromagnetic radiation. One is caused by the other; distance and efficiency. Electromagnetic induction has a principle of a primary coil generating a predominantly magnetic field and a secondary coil within the field

production needed to make India self-sufficient in food grains‚ thus improving agriculture in India. Hybrid high-yielding wheat was first introduced to India in 1963 by Dr. Norman Borlaug. Borlaug has been hailed as the Father of the Green Revolution. The methods adopted included the use of high yielding varieties(HYV) of seeds. The production of wheat has produced the best results in fueling self-sufficiency of India. Along with high yielding seeds and irrigation facilities‚ the enthusiasm of farmers mobilized
