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 the circuit for any given voltage applied to the circuit. This is according to Ohm’s law. The unit of resistance is the Ohm which has the Greek letter

What is peaceful resistance? We have seen many examples in history up even to today‚ in my case‚ even close to home. Peaceful resistance and non-violent protests is the practice of achieving goals through symbolic protests‚ civil disobedience‚ and noncooperation. The real question is with deaths of many great leaders and people throughout history with this "peaceful protest" is it a good thing? If you look at the outcomes‚ the positives outweigh the negatives. If colonial Indians hadn’t spoken-out

Tambrands- Overcoming Cultural Resistance Tambrands is a company who has flourished throughout North America and Europe yet it has faced many barriers that have prevented it from growing due to increased competition and its incapability to expand internationally. Tambrands specifically produces tampons and most of its sales are generated by the United States. Approximately 45% of Tambrands sales come from the U.S. yet Tambrands competes with companies such as Playtex and Kimberly-Clark. It is difficult

Societies who have had oppressed people used civil disobedience to bring attention to the injustices they have suffered. Peaceful resistance to laws positively impacts a free society because it is plays on the conscience of the oppressors and makes it easy for people to stand up for their own rights. Martin Luther King Jr. is a prime example as to why peaceful resistance to laws has a positive effect on a free society. King was a marquee figure in the civil rights movement in the 1960’s. King encouraged

The Life Cycle of Resistance to Change What is change? After doing some research I came discovered that there are many different definitions of the word change. Webster’s dictionary says that change means to give a different course‚ position‚ or direction to (Merrriam-Webster‚ 2010). Whenever you add the word change to organizational it takes on a somewhat different meaning. Organizational change is the term used to describe the transformation process that a company goes through in response to

Thermocouple comparison chart Resistance Temperature Detectors (RTDs) Resistance Temperature Detectors (RTDs) are sensors that measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is typically relatively fragile‚ so it is generally installed inside a sheath to protect it. The RTD element is constructed from a pure material‚ the resistance of which‚ at various temperatures

Theory: Thevenin theorem states that any linear two-terminal circuit can be replaced by an equivalent circuit consisting of a voltage source VTH in series with a resistance RTH where * VTH is the open-circuit voltage at the terminals‚ and * RTH is the equivalent resistance seen thru the terminals provided that all

Procedure Part I Wire Resistance: As wire length (cm) increases‚ the resistance (Ω) increases As wire area (cm2) increases‚ the resistance (Ω) decreases As wire resistivity (Ωcm) increases‚ the resistance (Ω) increases Procedure Part II: Ohm’s Law: Electricity‚ Magnets‚ and Circuits Ohm’s Law mA is milliamps‚ and 1000 milliamps equals one Ampere. Move the potential (volts) and resistance (ohms) sliders and observe the current (amps) As voltage increases‚ current increases. As resistance increases‚ current

ABSTRACT COOKSON‚ EDWARD JAMES. Development of the Metal Foam Electrical Resistance Heater. (Under the Direction of Dr. Albert Shih.) This thesis presents a novel concept using a radial heating element made from porous Fe-Cr-Al metal foam in an air heater. Electrical resistance heating has been used extensively to convert the electrical energy into thermal energy. An analytic heat transfer model is first developed to estimate dimensions of the heating element. Four prototype Fe-Cr-Al metal

The purpose maybe to increase productivity‚ capability‚ effectiveness and the organization`s ability. Although change is often necessary and important for organizations and individuals in order to survive or to develop. They typically demonstrate resistance to change. Managers have to develop new ideas to overcome this challenge.
