OHM LAW

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance,  one arrives at the usual mathematical equation that describes this relationship: 









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
