PPT-Electric Current, Resistance and Ohm’s law

Comparing shocks from static electricity and electric currents is like comparing apples and oranges they are similar but quite different at the same time Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal . and Ohm’s Law. The basics of electrical measurement. . Voltage is electrical pressure, which is potential force or the difference in electrical charge between two points. Voltage pushes electrical currents though a wire but not through its insulation.. Understanding Ohm’s Law. Copyright © Texas Education Agency, 2011. All rights reserved.. Copyright © Texas Education Agency, 2011. All rights reserved.. 2. Introduction. . What is Ohm. ’. s Law?. A . force. is a push or pull exerted on an object.. Energy. is the ability to do work or cause change.. Potential energy . is the stored energy that results from the position or shape of an object.. They convert the change in bend to electrical resistance , more the change more the value of resistance.. They are usually in the form of strips.. They can be made unidirectional and bidirectional.. FLEX sensor. Electric Current. Electric current . – The net movement of electric charges in a single direction through a wire or conductor.. Voltage difference . – The force that causes electric charges to flow; charges flow from high voltage to low voltage.. Key Points. Ohm’s Law. Resistivity. Electric Power. Alternating Current. References. . 18-1,2,3,4,5,6,7. Electric current is the rate of flow of charge through a conductor:. Unit of electric current: the ampere, . SPS10. Students will investigate the properties of electricity and magnetism.. Investigate static . electricity in terms of: friction, conduction, and induction.. Explain the flow of electrons in terms of:. This energy is given up to the load as the charges pass through the load. . Charge returns to the negative terminal of the battery with much less potential energy. Quantity. Symbol. Definition. Unit.

Electric Current Mr. Charge’s Journey Problem #1 The amount of charge that passes through the filament of a certain light bulb in 2 seconds is 1.67 C. A) What is the current in the light bulb? B) What is the number of electrons that pass through the filament in one second? Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . Dana . Olson.  Show some plots of impedance . curves. . perhaps even measure one actively live . Then he'll talk about what these curves mean,. how they are used and . What effect a 4 ohm vs 8 ohm speaker has on amplifier performance.. Electrons flow due to potential difference. If the potential difference is removed, then electrons stop flowing.. As electrons move, they bump into other atoms, this slows them down and impedes their motion..
