Ko te pūngao hiko te kaha o te hiko ki te mahi. He momo pūngao ka taea te huri ki ētahi atu momo pūngao, pērā i te pūngao miihini, te pūngao wera, te pūngao mārama rānei. Ka inehia te pūngao hiko i roto i ngā joule (J), engari i roto i ngā mahi o ia rā, ka inehia i roto i ngā kilowatt-haora (kWh), he waeine pūngao nui ake, he whai hua ake hoki hei whakamahi i roto i te horopaki o te whakapaunga hiko o te whare.
Ngā Mātāpono Taketake o te Pūngao Hiko
Ka taea te tatau i te pūngao hiko mā te whakamahi i te whārite taketake e whai ake nei:
\[ E = P \ngā wā t \]
kāore i te mana:
– Ko te pūngao i roto i ngā joule (J) ko \( E \)
– Ko te mana i roto i ngā watts (W) ko \( P \)
– Ko te wā i roto i ngā hēkona (s) ko \( t \)
I ngā horopaki o ia rā, ka inehia te wā i roto i ngā hāora, ā, ka inehia te mana i roto i ngā kilowati, nō reira ka tuhia pinepinetia tēnei whārite ki te āhua kilowati-hāora:

Ka taea te tatau i te mana hiko i roto i tētahi ara iahiko hiko mā te whakamahi i ētahi whārite i runga i ngā tawhā e mōhiotia ana:
1. Mō te ngaohiko (V) me te iahiko (I):
\[ P = V \ngā I \]
2. Mō te ngaohiko (V) me te ātete (R):
\[ P = \frac{V^2}{R} \]
3. Mō te au (I) me te ātete (R):
\[ P = I^2 \times R \]

\[ E = P \ngā wā t \]
Hei tauira, ki te whakamahi koe i tētahi mīhini horoi kakahu me te 500 watts o te mana mō ngā hāora e 2 i te rā, ko te whakapaunga hiko ko:
\[ E = 0.5 \, \text{kW} \times 2 \, \text{haora} = 1 \, \text{kWh} \]
Ki te whakamahia i ia rā mō te marama (30 rā), ko te tapeke o te pūngao e pau ana ko:
\[ 1 \, \text{kWh} \times 30 = 30 \, \text{kWh} \]
Te Whai Hua o te Pūngao
Ko te whai huatanga o te pūngao tētahi huarahi hei whakaiti i te whakapaunga pūngao me ngā utu hiko. Mā te whakamahi i ngā taputapu whai hua ake ka taea te penapena nui i te pūngao. Hei tauira, mā te whakakapi i ngā pūangi rama kanapa ki ngā pūangi rama LED, mā te whakamahi rānei i ngā taputapu he pai ake te whakatauranga pūngao.
