Whakamātautauhia te nekehanga raina tere ōrite

Kaupapa whakamātautau: Nekehanga rārangi tere ōrite

Ko te whāinga o te whakamātautau: – He mātakitaki i ngā mea e neke ana i te rārangi tika i te tere pumau.

– Kia mōhio ki te kauwhata whakaterenga-wā, te kauwhata tere-wā, te kauwhata tawhiti-wā

– Te tatau i te whakaterenga o tētahi mea

Ngā taputapu me ngā rauemi: Reriwe, pūtake hiko, kurupae maha-taumata, tereina hihiri, rekoata wā, rīpene, kawenga 50 karamu, taura hono.

Ngā taahiraa whakarite:

1. Huihuia ngā rēri, tāutahia te taputapu tuhi wā e ai ki te pikitia.

2. Whakatakotoria te kāreti hihiri ki te taha matau o te taputapu tuhi wā. Whakatakotoria he taumaha ki runga i te kāreti hihiri.

3. Tāpirihia te rīpene ki te taputapu hopu wā, ka honoa te pito o te rīpene ki te waka hikohiko.

4. Whakatakotoria te ngaohiko hiko ki te 12 volts

5. Honoa te pūhiko ki tētahi pūtake hiko, kātahi ka whakakā i te taputapu hopu wā.

6. Whakatakotoria te taputapu hopu wā kia tika te mahi

Ngā taahiraa whakamātautau:

1. Whakatītahahia te rēra

2. Whakakāhia te taputapu hopu wā

3. Tukua te tereina hihiri kia neke

4. Whakawetohia te taputapu hopu wā ina tae te tereina hihiri ki raro o te papa whakarara.

5. Tangohia te rīpene mai i te ara iahiko

Raraunga me te Tātari Raraunga:

Wā wā (t) = wā (T) = 1/f = 1/50Hz = 0,02 hēkona

Ko te 50 Hertz te auau PLN.

1. Inehia te tawhiti i waenganui i ngā pūwāhi tata e rua, tāuruhia ngā hua ine ki te ripanga raraunga, kātahi ka tātarihia ngā raraunga.

2. Tātaihia te tere mā te whakamahi i te tātai v = s/t, tāuruhia ngā hua ine ki te ripanga raraunga, ā, tātarihia ngā raraunga.

3. Tātaihia te whakaterenga mā te whakamahi i te tātai a = v/t, tāuruhia ngā hua ine ki te ripanga raraunga, kātahi ka tātarihia ngā raraunga.

4. Tuhia he kauwhata o te tawhiti (s) – te wā (t)

5. Tuhia he kauwhata o te tere (v) – te wā (t)

6. Tuhia he kauwhata o te whakaterenga (a) – te wā (t)
