Te Mārama ki ngā Porowhita Raupapa
Ko te ara iahiko raupapa he ara iahiko hiko e whakaritea ana ngā wāhanga kia kotahi anake te ara e rere ai te iahiko. I roto i te ara iahiko raupapa, ko ēnei wāhanga he ātete, engari ka uru atu hoki ki ngā pūnga hiko, ngā ine hiko, me ngā pūtake ngaohiko.
Ngā Āhuatanga o ngā Porowhita Raupapa
1. Ia Pūmau: He rite tonu te ia e rere ana i roto i ia wāhanga i roto i tētahi ara iahiko raupapa. Nā te mea kotahi anake te ara e rere ai te ia.
2. Te Whakarāpopototanga o te Ngaohiko: Ko te tapeke o te ngaohiko i roto i te ara iahiko raupapa he rite ki te tapeke o ngā hekenga ngaohiko puta noa i ia wāhanga. Nō reira, \( V_{total} = V_1 + V_2 + V_3 + … + V_n \).
3. Tāpiri Ātete: Ko te ātete katoa i roto i te ara iahiko raupapa ko te tapeke o ngā ātete o ia wāhanga. Nō reira, \( R_{total} = R_1 + R_2 + R_3 + … + R_n \).
Ngā Tātai Taketake
Ko ētahi tauira taketake hei maumahara mā te tātaritanga ara iahiko raupapa ko:
– Ngaohiko: \( V = I \whakanuia te R \)
– Ātete katoa: \( R_{total} = R_1 + R_2 + R_3 + … + R_n \)
– Te Ture a Ohm: \( I = \frac{V}{R} \)
Kia tika tā tātou haere ki ētahi tauira pātai me ā rātou matapakinga.

Tauira Pātai 1: Te Tātai i te Iahiko Katoa i roto i te Porowhita Raupapa
Pātai: Kei roto i tētahi ara iahiko raupapa e toru ngā ātete me ngā ātete \( R_1 = 2 \Omega \), \( R_2 = 3 \Omega \), me \( R_3 = 5 \Omega \). Mena ko te ngaohiko pūtake he 10 V, e hia te nui o te iahiko e rere ana i roto i te ara iahiko?
Kōrero:
Hipanga 1: Tātaihia te ātete katoa o te ara iahiko raupapa.
\[ R_{katoa} = R_1 + R_2 + R_3 \]
\[ R_{tapeke} = 2 \Omega + 3 \Omega + 5 \Omega \]
\[ R_{katoa} = 10 \Omega \]
Hipanga 2: Whakamahia te Ture a Ohm hei tatau i te iahiko katoa.
\[ I = \frac{V}{R_{katoa}} \]
\[ I = \frac{10 V}{10 \Omega} \]
\[ I = 1 A \]
Nō reira, ko te iahiko e rere ana i roto i te ara iahiko he 1 Ampere.
Tauira Pātai 2: Te Tātai i te Takahanga Ngaohiko puta noa i te Ātete
Pātai: I roto i te ara iahiko kotahi i te tauira pātai 1, he aha te hekenga ngaohiko puta noa i ia ātete?
Kōrero:
Hipanga 1: E mōhio ana tātou ki te tapeke o te iahiko i roto i te ara iahiko, arā, 1 A.
Hipanga 2: Whakamahia te Ture a Ohm hei tatau i te maturuturunga ngaohiko puta noa i ia ātete.
– Te hekenga o te ngaohiko puta noa i \( R_1 \):
\[ V_1 = I \whakareatia ki te R_1 \]
\[ V_1 = 1 A \whakareatia ki te 2 \Omega \]
\[ V_1 = 2 V \]
– Te hekenga o te ngaohiko puta noa i \( R_2 \):
\[ V_2 = I \whakareatia ki te R_2 \]
\[ V_2 = 1 A \whakareatia ki te 3 \Omega \]
\[ V_2 = 3 V \]
– Te hekenga o te ngaohiko puta noa i \( R_3 \):
\[ V_3 = I \whakareatia ki te R_3 \]
\[ V_3 = 1 A \whakareatia ki te 5 \Omega \]
\[ V_3 = 5 V \]
Hipanga 3: Manatokohia kei te ōrite te nui o te maturuturunga ngaohiko ki te ngaohiko pūtake.
\[ V_{tapeke} = V_1 + V_2 + V_3 \]
\[ V_{tapeke} = 2 V + 3 V + 5 V \]
\[ V_{katoa} = 10 V \]
Nō reira, ko ngā hekenga ngaohiko puta noa i ia ātete ko \( V_1 = 2 V \), \( V_2 = 3 V \), me \( V_3 = 5 V \).
Tauira Pātai 3: Te Whakatau i te Ātete o te Ātete i roto i te Ara iahiko
Pātai: Kei roto i tētahi ara iahiko raupapa ngā ātete e rua \( R_1 = 4 \Omega \) me \( R_2 = 6 \Omega \). Me tāpiri he ātete tuatoru ki te ara iahiko kia eke te ātete katoa ki te 15 \(\Omega\). He aha te uara o te ātete tuatoru?
Kōrero:
Hipanga 1: Tātaihia te ātete e hiahiatia ana hei whakatutuki i te 15 \(\Omega\).
\[ R_{katoa} = R_1 + R_2 + R_{3} \]
\[ R_{3} = R_{katoa} – (R_1 + R_2) \]
\[ R_{3} = 15 \Omega – (4 \Omega + 6 \Omega) \]
\[ R_{3} = 15 \Omega – 10 \Omega \]
\[ R_{3} = 5 \Omega \]
Nō reira, ko te uara ātete tuatoru e tika ana kia tāpirihia ko te 5 \(\Omega\).
Tauira Pātai 4: Te Tatau i te Mana e Pau ana i roto i te Porowhita Raupapa
Pātai: Hei tauira pātai 1, e hia te mana e pau ana i te ara iahiko katoa?
Kōrero:
Hipanga 1: Whakamahia te tātai mana hiko \( P = V \whakanuia ki te I \).
\[ P_{tapeke} = V_{tapeke} \times I \]
\[ P_{katoa} = 10 V \times 1 A \]
\[ P_{katoa} = 10 W \]
Nō reira, ko te mana e pau ana i te ara iahiko katoa he 10 Watts.
Hipanga 2: Manatokohia te mana e pau ana i ia ātete.
– Mana i te \(R_1\):
\[ P_1 = V_1 \ngā I \]
\[ P_1 = 2 V \whakanuia ki te 1 A \]
\[ P_1 = 2 W \]
– Mana i te \(R_2\):
\[ P_2 = V_2 \ngā I \]
\[ P_2 = 3 V \whakanuia ki te 1 A \]
\[ P_2 = 3 W \]
– Mana i te \(R_3\):
\[ P_3 = V_3 \ngā I \]
\[ P_3 = 5 V \whakanuia ki te 1 A \]
\[ P_3 = 5 W \]
Te nui o te mana e pau ana:
\[ P_{katoa} = P_1 + P_2 + P_3 \]
\[ P_{katoa} = 2 W + 3 W + 5 W \]
\[ P_{katoa} = 10 W \]
