PPT-Electric current is related to the voltage that produces it, and the resistance that opposes

Electric Current Notes Key Terms Voltage produces a flow of charge or current within a conductor The flow is restrained by the resistance it encounters The rate at which energy is transferred by electric current is . Instructor Name:. . (Your Name. ). 2. CHAPTER. Learning Objectives. Relate electrical terms including voltage, current, and resistance to their hydraulic or pneumatic counterpart. Explain the relationship among voltage, current and resistance in an electrical circuit. Voltage (. V. ) is the work (. W. ) per charge (. Q. ); it is responsible for establishing current.. Work is done as a charge is moved in the electric field from one potential to another. . Voltage is the work per charge done against the electric field. . 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. . BY HEI MAN KWOK 12N03S . 5.1 electric potential difference, current and resistance. Model of electric conduction in a metal – energy transfer . Charge carriers have kinetic energy . These collide with lattice ions . Electric circuits. what conducts electricity. what does and doesn’t conduct electricity. Current, voltage and resistance. Ohm’s Law. Power loss due to heat produced in a resistor. Simple circuit connections. Electric circuits. what conducts electricity. what does and doesn’t conduct electricity. Current, voltage and resistance. Ohm’s Law. Power loss due to heat produced in a resistor. Simple circuit connections. 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, . Objectives. Define voltage and give its unit of measurement.. Identify the two different types of voltmeters.. Connect a voltmeter in a circuit to measure voltage.. Use a digital multimeter to measure voltage.. Still waiting for . scantron. results…. Electric Current. Is the . flow of electric charge. (i.e. charged particles, usually electrons) . between regions of different electric potential. . . When there is no potential difference, there is no charge flow, no current.. 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. . Static Electricity.
