Misalai Ohm da yawa?
Ohm’s Law – Cikakken:
Cikakken Ohm na nufin cewa hanyoyin kadan da ya zama a kan fada shi yana dacewa da tsari a kan fadan shi, kuma yana juye da takardun fadan shi, inda tsaftaccen dogon mutanen yana kasancewa.
Amsa,
I yana nufin Hanyoyin Kadan,
V yana nufin Tsari, da
R yana nufin Takarda.
Triangle ta Cikakken Ohm:
Triangle ta Cikakken Ohm an samu ne a kan V, I, da R.
Cikakken Ohm ya ba da bayanan muhimman abubuwan da ke cikin circuits:
| MAIKATA | SYMBOL | SI UNIT | DENOTED BY | OHM’S LAW APPLICABLE |
|---|---|---|---|---|
| Hanyoyin Kadan | I | Ampere | A |  |
| Tsari | E or V | Volt | V |  |
| Takarda | R | Ohm | Ω |  |
Applications of Ohm’s law:
Yadda ake amfani da Cikakken Ohm:
1. Don in bincike mafi girman kayan aiki
2. Don in kirkiro sako mai fan
3. Don in bincike masarautar fuse
4. Don in bincike takarda mai resistor.
Limitations of Ohm’s law:
1. Ana iya amfani da Cikakken Ohm kawai a kan fadada metal. Saboda haka, ba za a iya yi wajen fadada kadan metal.
2. A nan gaban abubuwan elektrikal da ba su linealai, wasu kamar capacitance, resistance, k.a., ba za a iya kasancewa tsari da hanyoyin kadan da suka kasancewa da lokacin, saboda haka, ita ce ya fi karfi a yi amfani da Cikakken Ohm.
3. Transistors da diodes suna bi hanyoyin kadan zuwa farko, kafin ba su iya haɗa, saboda haka, ba za a iya amfani da Cikakken Ohm a kan waɗannan abubuwan elektrikal.
