Term
| 5.1.1 Define electric potential difference. |
|
Definition
| The work done per unit charge to move a positive test charge between A and B. |
|
|
Term
| 5.1.3 Define the electronvolt. |
|
Definition
| The energy that would be gained by an electron moving through a potential difference of 1 volt. |
|
|
Term
| 5.1.5 Define electric current. |
|
Definition
| The rate of flow of electrical charge. |
|
|
Term
|
Definition
| Resistance is a measure of how easily a charge can flow in a material. |
|
|
Term
|
Definition
Providing the physical conditions such as temperature are kept constant, the resistance is constant over a wide range of applied potential differences and therefore the potential difference
is directly proportional to the current. |

Term
| 5.1.9 Compare ohmic and non-ohmic behaviour. |
|
Definition
| In non-ohmic behavior V and I are not proportional to each other. Examples of this include light bulb filaments and semi-conductor devises like diodes and transistors. |
|
|
Term
