Lesson Plan: Electric Circuits (~130 minutes) Concepts 1. Electricity is the flow of electric charge (electrons). 2. Electric Charge is a property of subatomic particles. 3. Current is the movement of electric charge. 4. Voltage is the electric potential that exists to move a charge. 5. Power is the rate at which electric energy is flowing in a circuit. 6. Ohm’s Law: Power = Voltage x Current. 7. Resistance is a physical property that quantifies how well a charge

energy in the form of heat‚ to be transferred within the material‚ without any movement of the material itself. An easy way to understand this concept is through a simple demonstration. An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Well-insulated buildings need less energy for heating than buildings that have no insulation. Two building materials that are being used

Week #7 Chapter 10 Static and Current Electricity Exercises (p.221) 6. Strictly speaking‚ will a penny be slightly more massive if it has a negative charge or a positive charge? Explain. A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001

Static and Kinetic Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases

PaedDr. Dagmar Rusková‚ PhD. Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian American inventor‚ electrical engineer‚ mechanical engineer‚ and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system Tesla gained experience in telephony and electrical engineering before immigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers‚ setting up laboratories

Archimedes’ & Pascal’s Principle Purpose In this lab‚ we will prove Archimedes’ Principle by finding the density of a Metal Cylinder‚ a cork‚ and an unknown fluid by using Archimedes’ Principle. We will also use the PASCO Pascal’s Principle Lab Setup to investigate the use of fluid pressure as a hydraulic system to do work and we will find its mechanical advantage. Procedure For the first part of the lab we will be verifying case 3 as explained by professor. We

Extension English 1- Assessment Task 2-The Shipping News-Task 2(a) Formal Response-By Henri Rutherford Annie Proulx’s prose fiction novel ‘The Shipping News’ explores the complexities of individual’s navigation in our modern and increasingly globalised society. Proulx would agree with the statement ‘The global cannot be all bad nor the local all good. In our lives today‚ the two must coexist and we must learn to navigate both’‚ and her text provides evidence to this effect. The novel does not

displacement at each time step and results of previous time steps and the current time step are used with recurrence formulas to predict the acceleration and velocity at the current time step. A R.C.C. box structure is designed and analyzed by dynamic and static approach for various response ranges. Results show that dynamic analysis gives more economical and safer designs compared to other methods of analysis. Based on the understanding of results‚ a study on IS 4991:1968 is carried out and suitable suggestions
