Hukum Ohm (Materi Sekolah) /Ohm's Law (School Material)

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.

The equation of Ohm's Law are as follows:

I = V/R

V= R.I

R= V/I

R : Resistance (Ω/Ohm)
V : Voltage     (V/Volt)
I  : Electric Current (A/Ampere)

Example:
1. V = 4V
    R = 8Ω
    I  = V/R
       = 4V/8Ω
       = 0,5A

2. R = 6Ω
     I = 2A
    V = I.R
        = 2A.6Ω
        = 12V

3. I   = 4A
    V  = 12V
    R  = V/I
         = 12V/4A
         = 3Ω

Units of Ohm's Law:
1. Ampere (A)
2. Volt (V) = W/A = J/(A.s) = (N.m)/(A.s) = (kg.m²/s²)/(A.s) = (kg.m²)/(A.s³)
3. Ohm (Ω) = V/A = W/A² = J/(A².s) = (N.m)/(A².s) = (kg.m²/s²)/(A².s) = (kg.m²)/(A².s³)

That's all. Sorry if I made mistakes.
