Extended Experimental Investigation Generating Electricity Physics Teacher: Mr Heagney By: Jesse O’Sullivan Background Information: The history of electrisity leads right back to more than two thousand years ago. Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two. Many electricity-related discoveries had been made by the 17th century‚ including the differentiation between negative and positive currents‚ the classification of matireals as conductors

COMMON MISTAKES AND HOW TO AVOID THEM Phy X: ELECTRICITY 1. Topic Direction of flow of current. Common slips made Confusion between direction of flow of current and direction of movement of electrons Confusion in use of symbols- Is ampere written as A or amp. V=W/Q is often remembered wrongly. In questions where you have to check the resistance from the graph see what is plotted along the x and y axis. Reason why alloys are used to make elements of electric irons and heaters is not because

Lab #3: Isotonic contraction and the effect of load on skeletal muscles Abstract The job of the motor nervous system is to control certain elements in muscles simultaneously to ultimately produce movement. Movement of the body is the result of specialized cells directly associated with skeletal muscle. Skeletal muscles are voluntary muscle and must contract before movement can occur. We know the muscle team moving the arm is formed at the biceps and triceps. Biceps can bend the elbow‚ but

alternative for electricity generation in Nepal? “The sun bathes the earth in a steady‚ enormous flow of radiant energy that far exceeds what the world requires for electricity fuel.” The last decade has been harsh enough for the people of Nepal. The power cut being hiked up to 16 hours a day in 2009 provides testimony to the fact that Nepal has been hard hit by energy crisis. Given the over-increasing population‚ along with rapid industrialization and urbanization‚ the demand of electricity continues

Potentiality of Biomass Energy for Electricity Generation in Bangladesh Now a day’s worldwide energy crisis is one of the great problem. The interest in renewable energy has been revived over last few years‚ especially after global awareness regarding the ill effects of fossil fuel burning. The use of renewable energy technology to meet the energy demands has been steadily increasing for the past few years‚ however‚ the important drawbacks associated with renewable energy systems are their inability
