Misalan Tambayoyi 3 na Dokar Ohm
1. Dangane da bayanan da ke cikin teburin, ƙimar juriyar lantarki ita ce….. Shin bayanan da ke cikin teburin suna bayyana dokar Ohm?
Tattaunawa
R = V / I = 2 volt / 4 Ampere = 1/2 Ω
R = V / I = volts 4 / Amps 8 = 1/2 Ω
R = V / I = volts 3 / Amps 6 = 1/2 Ω
R = V / I = volts 5 / Amps 10 = 1/2 Ω
A bisa ga dokar Ohm, V/I yana nan daram. Don haka abubuwan da ke cikin teburin da ke sama suna bayyana dokar Ohm.
2. Wutar lantarki a cikin wani yanki na waya mai gudanarwa shine 4 A. Idan bambancin yuwuwar da ke tsakanin ƙarshen biyu shine Volts 12, menene juriya?
Tattaunawa
R = V / I = volts 12 / Amps 4 = 3 Ω
3. Shin bayanan da ke cikin teburin da ke ƙasa suna bayanin dokar Ohm?
Tattaunawa
Ƙimar juriyar lantarki bisa ga bayanai da ke cikin teburin ita ce:
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
Ƙimar V/I ba ta dawwama ba ce, don haka ba ta bayyana dokar Ohm ba. Dokar Ohm ta shafi idan ƙimar V/I ta kasance maiwwama.
