Komanso phunzirani zinthu zokhudzana ndi kukana kwamagetsi , zitsanzo za mavuto a resistor otsatizana , zitsanzo za mavuto a resistor ofanana.
Zitsanzo ziwiri za Mafunso Otsutsana ndi Magetsi
1. Chipangizo chamagetsi chimalumikizidwa ku gwero lamagetsi la 30 Volt ndipo chimakhala ndi mphamvu ya ma Ampere awiri. Dziwani kukana kwamagetsi kwa chipangizocho!
Zokambirana
Amadziwika kuti:
Mphamvu yamagetsi (V) = 30 Volts
Mphamvu yamagetsi (I) = 2 Ampere
Funso: Kukana kwa magetsi (R)
Yankho:
Fomula yotsutsa magetsi:
R = V / Ine
Kufotokozera: R = kukana kwa magetsi, V = magetsi amagetsi, I = magetsi amagetsi.
R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (werengani: Ohms).
2. Werengani kukana kwa magetsi kwa ma conductor angapo omwe ali ndi kutalika kwa mita imodzi ndi dera lopingasa la 1 x 10 -5 m2 . Kukana kwa ma conductor kwafotokozedwa mu tebulo ili m'munsimu.
Zokambirana
Fomula yotsutsa magetsi:
Kufotokozera: R = kukana kwamagetsi, ρ = kukana kwapadera, l = kutalika kwa kondakitala, A = dera lopingasa la kondakitala.
