Emergence of Modern ScienceElectricity and Magnetism NS 1300 Dr. Hoge
Coulomb’s Law • Electric charge • Electron flow
The Electric Field All that is solid is but the space between electrons the size of an atom black holes Electrons push with great force
The Flow of Electricity • Electric Potential (Voltage) • Electric Current (Amperage) • Resistance (Ohm’s Law)
Electric Circuits • Series Circuit • Parallel Circuit
Magnetism Magnetic Dipole Magnetic Field Electromagnetic Waves
Induction Motors Generators Transformers
Electric Power • P = I X V (power = work X time which is what you get when you multiply amps times volts)
Electric Currents • Direct Current • Alternating Current
Test Questions • An electron generates an electric charge. • Electric charge always flow from areas of high concentration to areas of low concentration. • As electric charge flows, it exerts a force on its surroundings. • The potential energy of this force (voltage) depends on the amount of charge available. • Electric current (amps) is the rate of flow of electric charge. • By overcoming resistance, electric charge can do work. • Electricity can be converted to other forms of energy. • A magnetic field is generated by the disproportionate distribution of electrons in a substance. • A magnet can be used to induce the flow of electrons. Flowing electrons can be used to induce a magnetic field. • Generators and transformers are technologies that utilize the principle of induction.
