Mafunso a chitsanzo cha lamulo la Ohm

Zitsanzo 3 za Mafunso a Malamulo a Ohm

1. Kutengera ndi deta yomwe ili patebulo, mtengo wa kukana kwamagetsi ndi….. Kodi deta yomwe ili patebulo ikufotokoza lamulo la Ohm?

Zokambirana

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

Malinga ndi lamulo la Ohm, V/I ndi yosasintha. Chifukwa chake zomwe zili patebulo pamwambapa zikufotokoza lamulo la Ohm.

2. Mphamvu yamagetsi mu waya woyendetsera magetsi ndi 4 A. Ngati kusiyana komwe kungatheke kumapeto onse awiri ndi 12 Volts, kodi kukana kwake ndi kotani?

Zokambirana

R = V / I = 12 volts / 4 Amps = 3 Ω

3. Kodi deta yomwe ili patebulo ili pansipa ikufotokoza lamulo la Ohm?

Zokambirana

Mtengo wotsutsa magetsi kutengera deta yomwe ili patebulo ndi:

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

Mtengo wa V/I si wokhazikika ndipo motero sufotokoza lamulo la Ohm. Lamulo la Ohm limagwira ntchito ngati mtengo wa V/I ndi wokhazikika.
