| Property of zero electrical resistance at a very low absolute temperature. |
|
|
Term
|
Definition
| Electrical resistivity is an intrinsic property that qualifies how strong a material opposes the flow of electrical current. |
|
|
Term
|
Definition
| An electrical resistor whose resistance is greatly reduced by heating. |
|
|
Term
|
Definition
A semiconductor device with two thermals, typically allowing the flow of current in one direction only.
or
A thermionic valve having two electrodes (anode and cathode). |
|
|
Term
|
Definition
-A closed circuit in which the current flows one path.
-Current is the same throughout.
-If one thing breaks than the circuit is broken. |
|
|
Term
|
Definition
-A open circuit in which the current is divided into two or more paths.
-Current is shared.
-Conserved current.
-If one thing breaks the circuit is not broken. |

Term
|
Definition
A measurement of the difference in electrical potential between two points in the circuit.
Volts (V) |
|
|
Term
|
Definition
A Materials opposition to the flow of electrical current.
Ohms |
|
|
Term
|
Definition
A way to induce voltage (emf), usually by making a charge in the magnetic environment of a coil of wire.
This charge can be made by changing the magnetic field strength. |

Definition
-Short for Electromagnetic Force.
-The energy per unit charge that is converted reversibly from energy to electrical energy in a battery. |
|
|
Term
|
Definition
The resistance within a battery or voltage source.
This causes a drop in source voltage (when there is a current). |
|
|
Term
|
Definition
| A number of resistors in a series, provided with a tap to make available a fixed or variable fraction, of the applied voltage. |
