Term
|
Definition
The electric potential enery per unity of charge, measure in volts, and often called voltage Electric Potential= Voltage: Charge |
|
|
Term
|
Definition
Conducting plates that seperate and store electrical charge. They have zero net charge since there are equal number of opposite charges. |
|

Term
|
Definition
Current (C/s) X Voltage (J/C) Watts (J/ s) |
|
|
Term
|
Definition
Usually a battery, that provides electrons through a voltage differents. A 9 volt batter is 9 volts/ coulomb of charge |
|
|
Term
|
Definition
An electric field that wiggles the electrons in a "back and forth" motion. Alternative current is require for magnetic induction. |
|
|
Term
|
Definition
A diode acts as a one way valve allowing electrons that flow in one direction to pass. Then a capacitor createds a retarding affect to even the motion, and supply a steady flow. |
|
|
Term
|
Definition
Each series is connected to the source so the voltage is the same. However, more current will flow throught the path of least resistance. The more series is in the circuit, the less the resistance. So the sum of all resistance is less and any one series. Resistance= 1/s1+ 1/s2+ 1/s3 |
|
|
Term
|
Definition
Voltage pass through one series before entering anther. The resistance applies seperately to each series. Resistance= S1+ S2+ S3 |
|
|
Term
|
Definition
An electric field is created in any region of space in which a magnetic field is changing with time. The magnitude is proportional to the rate that the magnetic field changes. The direction of the induced firld is at right angles of the changing magnetic field. |

Term
|
Definition
Uses a mechanical motion to spin a wire through magnetic field and created electrical energy. |
|
|
Term
|
Definition
Iron core wrapped around copper and is spun by steam or falling water through a magnetic field to created electric energy. |
|
|
Term
|
Definition
Using a stream of plasma that shoots through a magnetic field by combustion or nuclear compression to create electrical energy that is capture by plates. The wasted heat is used to steam water for steam turbine generators. |
|
|
Term
|
Definition
Creating magnetic induction by placing a primary coil next to a secondary coild. The change in magnetic field of the primary coil will create electricity to the secondary coil. # of loops = # of loops Voltage Voltage |
|
|
Term
|
Definition
A magnetic induction is created by change in the electric field. |
|
|
Term
Electromagnetic Induction |
|
Definition
Induction of voltage by change in magnetic field over time Voltage= # of loops X change in magnetic field/Time |
|
|
Term
|
Definition
The flow of electric enery over resistance. The appliance in the home provides the current. Current (Amps)= Voltage (J/C)/ Resistance (Ohms) |

Term
|
Definition
Atoms that have electrons that do not spin in opposite direction as to cancel out the magnetism. Iron, Cobalt, Nickel Iron atoms have 4 electrons whose electric spin is uncancelled |
|
|
Term
Charged Particles in Magnetic Field |
|
Definition
A moving charge particle that crosses the magnetic field will change direction so that it will be perpendicular to the magnetic field. The stronger the moving charge, the more perpendicular. The more perpendicular, the stronger the magnetic force. If it travels parallel to the magnetic field then there will be zero magnetic force, and no deflecting. |
|
|
Term
|
Definition
A stationary magnet in a coil. When electricity passes through the coil, then each coil will cause the magnet to react |
|
|
Term
|
Definition
Current is made to change direction of the coil by half rotation. Then coil continues in motion just in time for the current to reverse and force the coil to continue in another 1/2 rotation. Output: Mechanical energy |
|
|
Term
|
Definition
Current produces thermal and enery loss. So, power station step up the voltage to lower current. Then at substantion, voltage is step down for higher current. |
|

Term
|
Definition
Created from gravitation, comes in nuclear and gasoline. When it vibrate in the right frequency, then we can see electricity as light. |
|
|
Term
|
Definition
Charge is never created or destroyed |
|

Term
|
Definition
The electrical force is the charge of electron over distance |
|

Term
|
Definition
Loosly packed, outer shell, and therefore they are easiest to transfer and migrate |
|
