3 mau laʻana o nā nīnau e pili ana i ke kānāwai o Ohm
1. Ma muli o ka ʻikepili ma ka papa ʻaina, ʻo ka waiwai o ke kū'ē uila he….. Ke wehewehe nei anei ka ʻikepili ma ka papa ʻaina i ke kānāwai o Ohm?
Pahana
R = V / I = 2 volts / 4 Amps = 1/2 Ω
R = V / I = 4 volts / 8 Amps = 1/2 Ω
R = V / I = 3 volts / 6 Amps = 1/2 Ω
R = V / I = 5 volts / 10 Amps = 1/2 Ω
Wahi a ke kānāwai o Ohm, he paʻa ʻo V/I. No laila, wehewehe nā ʻike o ka papa ma luna i ke kānāwai o Ohm.
2. ʻO ke au i loko o kahi ʻāpana uea alakaʻi he 4 A. Inā he 12 Volts ka ʻokoʻa hiki ma nā wēlau ʻelua, he aha ke kū'ē?
Pahana
R = V / I = 12 volts / 4 Amps = 3 Ω
3. Ke wehewehe nei anei ka ʻikepili ma ka papa ma lalo nei i ke kānāwai o Ohm?
Pahana
ʻO ka waiwai kū'ē uila e pili ana i ka ʻikepili ma ka papa:
R 1 = V / I = 1,50 / 0,08 = 18,75 Ohms
R 2 = V / I = 2,80 / 1,50 = 2,87 Ohms
R 3 = V / I = 3,99 / 2,10 = 1,9 Ohms
ʻAʻole paʻa ka waiwai V/I a no laila ʻaʻole ia e wehewehe i ke kānāwai o Ohm. Pili ke kānāwai o Ohm inā paʻa ka waiwai V/I.
