2 Tauira o ngā Pātai Ātete Hiko
1. Kua honoa tētahi taputapu hiko ki tētahi pūtake hiko 30 Volt, ā, e 2 Amperes te iahiko e mau ana. Tātaihia te ātete hiko o te taputapu!
Kōrero
E mōhiotia ana:
Ngaohiko hiko (V) = 30 Volts
Iahiko hiko (I) = 2 Ampere
Pātai: Ātete hiko (R)
Whakautu:
Te tātai ātete hiko:
R = V / I
Whakaahuatanga: R = ātete hiko, V = ngaohiko hiko, I = iahiko hiko.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (pānuihia: Ohms).
2. Tātaihia te ātete hiko o ētahi kaiārahi hiko he 1 mita te roa, ā, he 1 x 10 -5 m² te horahanga whakawhiti . Kei te ripanga i raro nei te ātete o ngā kaiārahi hiko.
Kōrero
Te tātai ātete hiko:
Whakaahuatanga: R = ātete hiko, ρ = ātete motuhake, l = roa o te ara iahiko, A = horahanga whakawhiti-wāhanga o te ara iahiko.
