Investigation Calvin Chang 8.2 Stage 1: Planning the Experiment Introduction ! By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of the battery‚ the type of wire you are using‚ how long the

will an electric heater coil draw from a 220 volt line‚ if the resistance of the heater coil is 40? (1 Mark) (Ans) Given‚ R= 40‚ V=220 V We have the relation‚ I = V/R = 220/40 = 5.5 A 2. What is electric current? (1 Mark) (Ans) The rate of flow of charge per unit time through a conductor is called electric current. 3. What is the SI unit of electric current?

It is difficult and sometimes impossible to work in an office where there is no light and fan. Students read comfortably in a room which is properly furnished with electric light and fan. Fan is not a luxurious thing. It is necessary to fight heat during summer. Electricity is essential to operate fan in summer and electric heater

Calculate the electric force between two point charges of 4.00 µC and 3.00 µC when they are 2.00 cm apart. 2. Two points of equal charge produce an electric force on each other of 3.40x10 -2 N when placed 0.100 m apart. What is the charge on each point? 3. How far apart are two point charges of 2.0x10-6 C and 4.0x10-6 C if they produce an electric force of 0.56 N? 4. Two

electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming light and the re-radiation. In the backward direction we normally call the re-radiation "reflection

Switch Completely to Electric Cars? Everyday gas powered cars destroy the environment and the people that drive these gas guzzlers pay a ton of money to use them. Many people think that gas powered cars are better than electric cars‚ but they do not know the real truth. After you read this paper you will understand why electric cars are better for yourself and the environment; you might even have to buy one! There are many credible sources that prove the benefits of having an electric car and describe

Electric cars have been around for a very long time. An electric car is powered by a battery instead of an engine. Surprisingly‚ they have existed longer than gasoline powered vehicles. A related technology is the gasoline/electric hybrid car‚ and they are powered by both large batteries and gasoline engines. Although initially more expensive‚ electric cars and hybrid cars cause a deduction in environmental destruction because they have higher fuel efficiency‚ reduced air pollutants‚ and less petrochemical
