Loaʻa i kahi capacitor kahi capacitance kikoʻī. Inā ʻaʻole loaʻa ka capacitance i koi ʻia, hiki ke hoʻopili ʻia ʻelua a ʻoi aku paha nā capacitors e hoʻokō i ka capacitance i koi ʻia. No ka hoʻopili pono ʻana i nā capacitors, he mea nui ka hoʻomaopopo piha ʻana i nā kaapuni capacitor.
Ma mua o ke aʻo ʻana i nā kaapuni capacitor, e hoʻomaopopo mua i nā hōʻailona. 
Eia aʻe. Hōʻike nā laina kū ʻelua i ka hōʻailona capacitor i nā alakaʻi ʻelua i loko o kahi capacitor parallel-plate. I ka hōʻailona pila, hōʻike ka laina kū lōʻihi i ka hiki ke kiʻekiʻe (+) a hōʻike ka laina kū pōkole i ka hiki ke haʻahaʻa (-). Hōʻike nā laina ākea i nā hōʻailona capacitor a me ka pila i nā uea.
Kaapuni Moʻo
ʻElua mau capacitors i hoʻopili ʻia e like me ka mea i hōʻike ʻia ma ka hema ua kapa ʻia he capacitors ma ke ʻano series. Hōʻike ke kiʻi ma ka ʻākau i kahi capacitor pani me kahi capacitance e like me nā capacitors ʻelua i hoʻopili ʻia ma ke ʻano series.
I ka wā mua, ʻaʻole i hoʻouka uila ʻia nā capacitors ʻelua. Ma hope o ka hoʻopili ʻia ʻana i ka pila, lilo ka papa luna o ka capacitor C1 i hoʻopili ʻia i ka pou maikaʻi o ka pila i hoʻouka maikaʻi ʻia no ka mea e neʻe ana nā electrons mai loko mai a ʻo ka papa lalo o ka capacitor C2 i hoʻopili ʻia i ka pou maikaʻi ʻole o ka pila i hoʻouka maikaʻi ʻia no ka mea loaʻa iā ia nā electrons. Neʻe nā electrons i hoʻouka maikaʻi ʻia no ka mea ua huki ʻia lākou e ka pou maikaʻi o ka pila i hoʻouka maikaʻi ʻia. A laila, ua kipaku ʻia kēia mau electrons e ka pou maikaʻi ʻole o ka pila i hoʻouka maikaʻi ʻia i ka papa lalo o ka capacitor C2 . ʻO ka papa luna o ka capacitor C1 i hoʻouka maikaʻi ʻia e huki i nā electrons mai ka papa luna o ka capacitor C2 i neʻe ai nā electrons i ka papa lalo o ka capacitor C1 . ʻO ka hopena, lilo ka papa lalo o ka capacitor C1 i hoʻouka maikaʻi ʻia a lilo ka papa luna o ka capacitor C2 i hoʻouka maikaʻi ʻia.
ʻO ka uku maikaʻi ʻole e puka mai ana mai ka papa luna o ka capacitor C 1 ua like ia me ka uku maikaʻi ʻole e komo ana i ka papa lalo o ka capacitor C 2 a loaʻa i ka papa luna o ka capacitor C 1 kahi uku maikaʻi e like me ka uku maikaʻi ʻole e puka mai ana mai loko mai. Pēlā nō, ʻo ka uku maikaʻi ʻole ma ka papa lalo o ka capacitor C 1 ua like ia me ka uku maikaʻi ma ka papa luna o ka capacitor C 2. No laila, loaʻa i kēlā me kēia papa alakaʻi ka nui o ka uku akā ʻokoʻa ka hōʻailona, kahi i loaʻa ai i ka papa luna o ka capacitor C 1 kahi uku o +Q, ʻo ka papa lalo o ka capacitor C 1 kahi uku o -Q, ʻo ka papa luna o ka capacitor C 2 kahi uku o +Q a ʻo ka papa lalo o ka capacitor C 2 kahi uku o -Q. I loko o kahi kaapuni moʻo, ʻo ka nui o ka uku uila ma ka capacitor C 1 (Q 1 ) = ka nui o ka uku uila ma ka capacitor C 2 (Q 2 ) = Q.
Pehea e pili ana i ka hiki ke uila? I loko o kahi kaapuni moʻo, ua like ka hiki ke uila ma ka capacitor pani me ka hiki ke uila ma kēlā me kēia capacitor, V = V1 +V2. Ka hiki ke uila ma luna o ka capacitor C1 ʻo V1 = Q/C1, ka mana uila ma ka capacitor C2 ʻo V2 = Q/C2 a ʻo ka mana uila ma ka capacitor pani ʻo V = Q/C.
V = V1 +V2
Q/C = Q/C1 + Q/C2
Q/C = Q (1/C1 + 1/C2)
1/C = 1/C1 + 1/C2
Inā he ʻekolu mau capacitors i hoʻopili ʻia ma ke ʻano series, e loli ke ʻano ma luna nei i:
1/C = 1/C1 + 1/C2 + 1/C3
Inā he ʻehā mau capacitors a laila e hoʻohui i ka 1/C4. Pēlā nō, inā he ʻelima mau capacitors, a pēlā aku. ʻO kēia ke ʻano hana no ka hoʻoholo ʻana i ka capacitance o ka capacitor pani no nā capacitors i hoʻopili ʻia ma ke ʻano series.
Manaʻo ʻia ʻo C1 ʻo 2 a me C2 ʻo 1 a laila ʻo ka capacitance o ka capacitor pani:
1/C = 1/C1 + 1/C2 = 1/2 + 1/1 = 1/2 + 2/2 = 3/2
C/1 = C = 2/3
Ma muli o kēia helu ʻana, ua hoʻoholo ʻia ʻoi aku ka liʻiliʻi o ka capacitance o ka capacitor pani ma mua o ka capacitance o kēlā me kēia capacitor i hoʻopili ʻia ma ke ʻano series.
Kaapuni Hoʻohālikelike
ʻElua mau capacitors i hoʻopili ʻia e like me ka mea i hōʻike ʻia ma ka hema ua kapa ʻia he mau capacitors parallel. Hōʻike ke kiʻi ma ka ʻākau i kahi capacitor like me ka capacitance e like me nā capacitors ʻelua i hoʻopili ʻia ma ke ʻano parallel.
Ua pili nā papa luna o nā capacitors C1 a me C2 i ke kikowaena maikaʻi o ka pila, no laila he kiʻekiʻe ko lākou hiki ke uila. I kēia manawa, ua pili nā papa lalo o nā capacitors C1 a me C2 i ke kikowaena maikaʻi ʻole o ka pila, no laila he haʻahaʻa ko lākou hiki ke uila. No laila, hiki ke hoʻoholo ʻia he ʻokoʻa hiki kēlā me kēia capacitor i hoʻopili ʻia ma ke ʻano like me ka ʻokoʻa hiki o ka pila (V1 = V2 = V).
Ke hoʻopili ʻia nā capacitors ʻelua like i kahi pila, huki ka pou maikaʻi o ka pila i nā electrons i ka papa luna ʻoiai ʻo ka pou maikaʻi ʻole o ka pila e kipaku i nā electrons i ka papa lalo, e hoʻoneʻe ana i nā electrons mai ka papa luna a i ka papa lalo. Nalowale nā papa luna ʻelua i nā electrons, e lilo i mea hoʻopiʻi maikaʻi, a loaʻa i nā papa lalo ʻelua nā electrons, e lilo i mea hoʻopiʻi maikaʻi ʻole. Hoʻopau ka hoʻoili ʻana o ka electron i ka wā e like ai ka ʻokoʻa o ka potential ma waena o nā papa alakaʻi ʻelua me ka ʻokoʻa o ka potential o ka pila.
ʻO ka papa luna o ka capacitor C 1 a me ka papa lalo o ka capacitor C 1 e mālama i ka uku uila like akā he mau hōʻailona kū'ē. Pēlā nō, ʻo ka papa luna o ka capacitor C 2 a me ka papa lalo o ka capacitor C 2 e mālama i ka uku uila like akā he mau hōʻailona kū'ē. Inā ʻo ka uku uila i mālama ʻia i loko o ka capacitor C 1 ʻo Q 1 a ʻo ka uku uila i mālama ʻia i loko o ka capacitor C 2 ʻo Q 2 a laila ʻo ka uku uila holoʻokoʻa i mālama ʻia i loko o nā capacitor ʻelua i hoʻopili ʻia ma ke ʻano like ʻo Q = Q 1 + Q 2. No laila, ʻo ka uku uila holoʻokoʻa i loko o nā capacitor i hoʻopili ʻia ma ke ʻano like ua like ia me ka huina o nā uku i loko o kēlā me kēia capacitor.
Ua helu ʻia ka nui o ka uku uila ma kēlā me kēia capacitor i hoʻopili ʻia ma ke ʻano like me ka hoʻohana ʻana i ka hoohalike Q1 = C1 ʻO ΔV a me Q2 = C2 ʻO ΔV ʻoiai ua helu ʻia ka nui o ka uku uila ma ka capacitor pani me ka hoʻohana ʻana i ka hoohalike Q = C ΔV, kahi ʻo Q ka uku uila, ʻo C ka capacitance a ʻo ΔV ka ʻokoʻa hiki ke uila. ʻO ka hoohalike Q = Q1 +Q2 hoʻoponopono hou ʻia ma ka hoʻololi ʻana iā Q:
Q = Q1 +Q2
C ΔV = C1 ΔV + C2 V
C ΔV = ΔV (C1 +C2)
C = C1 +C2
Ua like ka ʻokoʻa hiki ke ΔV a no laila ua hoʻopau ʻia mai ka hoohalike.
Inā ʻekolu mau capacitors i hoʻopili ʻia ma ke ʻano like, e loli ke ʻano ma luna nei i:
C = C1 +C2 +C3
Inā he ʻehā mau capacitors a laila hoʻohui ʻia ʻo C4Pēlā nō, inā he ʻelima mau capacitors, a pēlā aku. ʻO kēia ke ʻano hana no ka hoʻoholo ʻana i ka capacitance o ka capacitor pani no nā capacitors i hoʻopili ʻia ma ke ʻano like.
Manaʻo ʻia ʻo C1 ʻo 2 a me C2 ʻo 1 a laila ʻo ka capacitance o ka capacitor pani:
C = C1 +C2 2 + 1 = 3
Ma muli o kēia helu ʻana, ua hoʻoholo ʻia ʻoi aku ka nui o ka capacitance o ka capacitor pani ma mua o ka capacitance o kēlā me kēia capacitor i hoʻopili ʻia ma ke ʻano like.
