Where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
The VIR triangle.
You can use the VIR triangle to help you remember the three versions of Ohm's Law.
Write down V, I and R in a triangle like the one in the yellow box on the right.
- To calculate voltage, V: put your finger over V, this leaves you with I R, so the equation is V = I × R
- To calculate current, I: put your finger over I, this leaves you with V over R, so the equation is I=V/R
- To calculate resistance, R: put your finger over R, this leaves you with V over I, so the equation is R=V/I

that's good benny..
but I want to ask you, what kind of experiments that using the application of Ohm's Law.
thank you
What application can be used from ohm's law?
Give an example of experiments that can applied to the law of ohm ?
