| OHM's LAW | ||||
|
Ohm investigated the relation between the intensity of a current which flows through an element in a circuit and the potential difference between the two ends of this element. To reproduce his investigation we will use two devices you are already familiar with:
|
 |
 |
 |
 |
The concept of a circuit | |
 |
 |
 |
|
The hydraulic simile | |
|
Elements in the circuit | |
|
Characteristic magnitudes | |
