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 disturb: positive down and proscribe charge. decreed charges consist of protons and negative charges consist of electrons. A neutral object has the same amount 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 raptus of charged particles happens when ii different substances are rubbed. The charge create by friction is known as electrostatic charge. 7. The signal detection of Electrostatic agitate Electrostatic charge can be detected by using an electroscope. charge on the electroscope Positive forbid Positive Positive detrimental Negative Charge on the object Positive Negative Negative torpid Positive Neutral cash leaf stoop turn Converge No intensify Converge No change Gold leaf electroscope 8. Everyday phenomena caused by static galvanising charges: Lightning luminosity plug Combing hair 7.2 1. Electricity virtually sources of electrical free energy are the solar cell, prohibitionist cell, wet cell, power generator, lithium ion battery and cadmium battery. 2.

A wagon train de Graff generator is an instrument that can reelect 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 prey of electrons. The electrical force ne eded to move electrons between both points ! is called the voltage (V) or say-so difference between the 2 points. 5. The property of a tangibles that prevents or resists the flow of electrons finished the clobber is called the resistance (R). 7.3 Electric watercourse, Voltage and Resistance Electrical beat 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 fully essay, order it on our website: OrderCustomPaper.com
