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 . Resistance. and. resistivity. Learning. . outcomes. Candidates should be able to:. (. g) define resistance and the ohm. (h) recall and solve problems using V = IR. (. i. ) sketch and explain the I-V characteristics of a metallic conductor . Nicolo. . Maganzini. , Geronimo . Fiilippini. , . Aditya . Kuroodi. 2015. Relevant Course(s): EE10, EE11L. Resistors in Networks. 2. What are we learning?. Learn about the math behind networks of resistors.. 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..

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.. Lesson 5. Resistance. The amount of current flow in a circuit, and the amount of energy transferred to any useful device, depends on two things; . The potential difference of the power supply. The nature of the pathway through the loads that are using electric potential energy. . 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.. Perfect conductors. carry charge instantaneously from here to there.
