E aʻo pū i nā mea e pili ana i ke kū'ē uila , nā laʻana o nā pilikia resistor series , nā laʻana o nā pilikia resistor parallel.
2 mau laʻana o nā nīnau kū'ē uila
1. Ua hoʻopili ʻia kahi mea uila i kahi kumu mana 30 Volt a lawe i ke au o 2 Amperes. E hoʻoholo i ke kū'ē uila o ka mea hana!
Pahana
Ua ʻike ʻia:
Ka uila uila (V) = 30 Volts
Au uila (I) = 2 Amperes
Nīnau: Ke kū'ē uila (R)
Pane:
ʻO ke ʻano pale uila:
R = V/I
Wehewehena: R = ke kū'ē uila, V = ka uila uila, I = ke au uila.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (heluhelu ʻia: Ohms).
2. E helu i ke kū'ē uila o kekahi mau alakaʻi uila nona ka lōʻihi o 1 mika a me kahi ʻāpana kea o 1 x 10 -5 m2 . Ua hōʻike ʻia ke kū'ē o nā alakaʻi uila ma ka papa ma lalo nei.
Pahana
ʻO ke ʻano pale uila:
Wehewehe: R = ke kū'ē uila, ρ = ke kū'ē kiko'ī, l = ka lōʻihi o ke alakaʻi, A = ka ʻāpana ʻāpana o ke alakaʻi.
