- karabo: Bakeng sa thepa e mengata, khanyetso e eketseha ha mocheso o ntse o phahama. Palo eo khanyetso e fetohang ka eona ha mocheso o ntse o phahama e khethoa ke tekanyo ea khanyetso ea mocheso oa thepa. Li-resistor tse ling li etselitsoe ka ho khetheha ho ba le phetoho e nyane ha mocheso o ntse o phahama (tsena li bitsoa li-resistor tse tsitsitseng tsa mocheso kapa tse nang le mocheso o tlase).
Ke hobane'ng ha li-resistors tsa ho hula holimo le ho hula fatše li sebelisoa lipotolohong tsa dijithale?

karabo: Li-resistor tsa ho hula holimo le ho hula tlase li sebelisoa ho hlalosa boemo ba kamehla (bo sa sebetseng) ba phini ea ho kenya ea dijithale. Resistor ea ho hula holimo e hokahanya phini ea ho kenya le motlakase o motle ha ho se na lets'oao le sebetsang le sebelisitsoeng, ho netefatsa boemo ba kamehla ba HIGH. Ka lehlakoreng le leng, resistor ea ho hula tlase e hokahanya phini ea ho kenya fatše, ho netefatsa boemo ba kamehla ba LOW.
