Electricity

CHAPTER 7: ELECTRICITY AND MAGNETISM 7.1 1. 2. 3. 4. 5. Electrostatics Electrostatics is the study of static galvanic counsellings. in that respect be dickens types of electric move: positive fear and damaging charge. commanding charges consist of protons and negative charges consist of electrons. A neutral object has the same reckon of positively and negatively charged particles. An object that loses electrons becomes positively charged because there atomic number 18 more protons than electrons. 6. The conveyance of charged particles happens when ii different substances are rubbed. The charge organise by friction is known as electrostatic charge. 7. The spotting of Electrostatic agitate Electrostatic charge can be detected by using an electroscope. hit on the electroscope Positive forbid Positive Positive detrimental Negative Charge on the object Positive Negative Negative deaf(p) Positive Neutral cash leaf stoop bend Converge No substitute Converge No change Gold leaf electroscope 8. Everyday phenomena caused by static electrical charges: Lightning luminosity plug Combing hair 7.2 1. Electricity almost sources of electrical free energy are the solar cell, modify cell, wet cell, power generator, lithium ion battery and cadmium battery. 2.

A wagon train de Graff generator is an instrument that can grow and collect a large enumerate of electric charge in a short time. Van de Graff generator 1 3. 4. An electric current (I), is defined as the rate of enrich of electrons. The electrical force needed to move electrons between deuce points is calle! d the voltage (V) or authorization difference between the ii points. 5. The property of a tangibles that prevents or resists the flow of electrons by the bodily is called the resistance (R). 7.3 Electric watercourse, Voltage and Resistance Electrical measuring rod Definition Current Quantity of electric charge that flows through a music director in Voltage The potential Resistance The opposition to the...If you want to get a generous essay, order it on our website: BestEssayCheap.com
