Akohia hoki ngā tauira o ngā ātete whakarara me ngā tauira o ngā ātete raupapa.
Rauemi Ātete Raupapa
Mena ka honoa ngā ātete e ai ki te hoahoa i runga ake nei, ka honoa raupapatia. Ko ngā ātete e pā ana ki tēnei he wāhanga ātete, he rama, he taputapu ārai hiko rānei.
He pumau te utu hiko (Q) kia rite ai ki te utu hiko e neke ana i roto i te ātete 1 (R1 ) = te utu hiko e neke ana i roto i te ātete 2 (R2 ) = te utu hiko e neke ana i roto i te ātete 3 (R3 ) . Ko te iahiko (I) te utu hiko e rere ana i roto i tētahi wā kua whakaritea (I = Q/t), nō reira ko te iahiko e haere ana i roto i te ātete 1 (I1 ) = te iahiko e haere ana i roto i te ātete 2 (I2 ) = te iahiko e haere ana i roto i te ātete 3 (I3 ) . I roto i te pāngarau, ko te iahiko katoa (I) = I1 = I2 = I3.
I tētahi atu taha, ka heke te ngaohiko hiko (V) ina neke te utu hiko i roto i ia ātete. Ko te ngaohiko hiko, e kiia ana ko te rerekētanga pūmanawa hiko, ko te pūngao pūmanawa hiko mō ia waeine o te utu hiko. Ka heke te ngaohiko hiko nā te mea ka whakamahia te pūngao hiko i roto i ia ātete hiko. Nō reira, ko te ngaohiko hiko katoa (V) he ōrite ki te tapeke o ngā ngaohiko hiko i runga i ia ātete. I roto i te pāngarau, ko te ngaohiko hiko katoa (V) = V1 + V2 + V3 . V = IR kia rite ai te whārite ngaohiko hiko katoa V = IR1 + IR2 + IR3 . He rite tonu te iahiko hiko e rere ana i roto i ia ātete, nō reira ka huri tēnei whārite ki V = I (R1 + R2 + R3 ).
I runga i te whārite i runga ake nei, ka whakatauhia ko te ātete hiko katoa (R) te ātete whakakapinga rānei o te ātete hiko e honoa raupapa ana he ōrite ki te tapeke o ia ātete hiko, i runga i te pāngarau R = R1 + R2 + R3 . Mena e rua noa iho ngā ātete e honoa raupapa ana, ko te uara ātete whakakapinga (R) = R1 + R2 . Mena e whā ngā ātete e honoa raupapa ana, ko te uara ātete whakakapinga (R) = R1 + R2 + R3 + R4 . Waihoki, mena e rima, neke atu rānei i te rima ngā ātete e honoa raupapa ana.
Tauira o te raruraru ātete raupapa:
1. E hoatu ana ko R 1 = 2 Ω, R 2 = 3 Ω me R 3 = 4 Ω. E honoa ana ngā ātete e toru i roto i te raupapa. He aha te uara o te ātete whakakapinga? (Ω = Ohm).
Kōrero
R = R1 + R2 + R3 = 2 + 3 + 4 = 9 Ω.
E whakaatu ana tēnei hua he nui ake te uara ātete whakakapinga i te uara ātete o ia ātete e honoa raupapa ana.
2. E rua ngā ātete R 1 = 50 Ω me R 2 = 50 Ω e honoa ana i roto i te raupapa, ā, e honoa ana ki tētahi pākahiko 12 Volt. Tātaihia (a) te ātete ōrite (b) te iahiko e puta ana i roto i ia ātete.
Kōrero
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Ngā Waohiko / 100 Ω = 0,12 Āpere
