- A device that has a graph of current versus voltage that is not a straight line. A device that cannot be treated as an ordinary resistor. | |
Normalise |
- Is to represent a number in an agreed floating point notation in order to avoid the problem of multiple representations. The form chosen is usually that which provides maximum precision. |
|
Normalized Variable |
- A variable that has been divided by another variable with the same units or dimensions | |
