7. Chii chinoitika kana resistor iri muchikamu chakafanana ikakundikana (yakavhurika)?
   • mhinduro: Kana resistor iri muparallel circuit ikakundikana nekuva open circuit, mamwe matavi akaenzana acharamba aine current. Kuramba kwese kwecircuit kuchawedzera sezvo imwe yenzira dzakafanana yabviswa.
8. Sei mamwe maseketi achishandisa ma resistors ane resistance yakakwira kwazvo, dzimwe nguva akafanana ne megaohms?
   • mhinduro: Kukosha kwakanyanya kwekudzivirira kunogona kushandiswa pazvinangwa zvakasiyana-siyana, zvakaita sekugadzira ma voltage dividers, biasing transistors, kana kushanda nema current applications akaderera zvikuru. Anogona kuve nechokwadi chekuti current inoyerera zvishoma mune zvimwe zvikamu zvema circuit, kunyanya panodiwa kunzwisisa kana kunyatsojeka.
9. Kupisa kunokanganisa sei kuramba kwevazhinji vanodzivisa?
   • mhinduro: Pazvinhu zvakawanda, kuramba kunowedzera nekupisa. Huwandu hwekuchinja kwekuramba nekupisa hunoenderana nekupisa kwechinhu chacho. Mamwe ma resistors akagadzirirwa kuti ave nekuchinja kudiki mukuramba nekupisa (aya anonzi ma resistors anogadzikana kana kuti ma resistors ane temperature yakaderera).
10. Sei zvinodzivirira kudhonza-kumusoro nekudhonza-pasi zvichishandiswa mumasekete edhijitari?

• mhinduro: Zvinodzivirira kudhonza-kumusoro nekudhonza-pasi zvinoshandiswa kutsanangura mamiriro edhijitari (asina basa) epini yedhijitari. Zvinodzivirira kudhonza-kumusoro zvinobatanidza pini yekupinda kune voltage yakanaka kana pasina chiratidzo chinoshanda, zvichiita kuti pave nemamiriro eHIGH. Kusiyana neizvi, zvinodzivirira kudhonza-pasi zvinobatanidza pini yekupinda pasi, zvichiita kuti pave nemamiriro eLOW.
