| - | Ohmi seadust kasutatakse elektrijuhile rakendatud pinge ja juhti läbiva voolutugevuse vahelise sõltuvuse iseloomustamiseks. Iseloomustav tegur on juhi takistus ehk juhi omadus elektrilaengute liikumist takistada. Ohmi seaduse sõnastas Georg Simon Ohm järgmiselt: | + | Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them, provided that the temperature remains constant. |
| - | [{{ : | + | The equation is as follows: |
| + | [{{ : | ||
| I = U / R | I = U / R | ||
| - | kus: | + | where: |
| - | * I on voolutugevus | + | * I is current |
| - | * U on pinge | + | * U is voltage |
| - | * R on takistus | + | * R is resistance |
| - | Ohmi seadusest on tuletatud mitmeid teisi valemeid, mida elektroonikas igapäevaselt kasutatakse. | + | |
| + | Several other equations that are used often in electronics are derived from Ohm's law. | ||
