Electricity and Magnetism
Electicity
Charges can move one place to another
Static charges have potential energy
Electric Potential Energy
Electric Potential
Electric Potential - the amount of electric Potential energy per unit charge at a certain position in a electric feild
Volt - The measurement of electric potential
Lightning
Charge Movement
Materials affect charge movement
Conductors and Insulators
Conductor - Material that allows an electric charge to pass through it easily
Insulator - Material that does not easily allow a electric charge to pass through
Resistance
Resistance - Material that resists the movement of a charge in different amounts
Ohms - The unit that measures electrical resistance
Superconductors
Grounding
Grounding - providing a harmless low-resistance path for electricity to fallow
Electric current is a flow of charge
Electric charge can flow continuusly
Electric current - A flow of charge
Current, Voltage, and Resistance
Ampere - The standerd unit of measurement for current
Ohm's Law
Ohm' s Law - the relationship between current, voltage, and resistance
Measuring Electricity
Electric cells supply electric current
Electric cells - a try of device that can produce current using the chemical or physical properties of the material
Electrochemical Cells
Solar cells
Materials can become electrically charged
Electric charge is a property of matter
Electric charge - is a property that allows an object to exert an electric force on another object without touching it
Electric field - An electric field is a force that pushes and pulled the space around a particle through an electric charge
Static charges are caused by the movement of electons
Charging by contact
Static charges - is a buildup of electric charge in an object caused by the presence of many particles with the same charge,
How Materials Affect Static Charging
Charging by Induction
Induction - The buildup of a charge without direct contact
Charge Polarization
Technology used static electrucuty
Magnetism
Circuits and Electonics
Circuits made electric currents useful PAGE 50
Electronic technology is based on circuits
Charge needs a cointinous path to flow
Electric change flows in a loop
Circuit - a closed path through which a countinous charge can flow
The parts of a circuit
Open and closed circuits
Current follows the path of least resistance
Short circuits
short circuit - path connections one part of a circuit with another
Grounding a circuit
Safety devices control current
How fuses work
Other safety devices
