Ohm’s Law
Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.
V =IR
This can be formally stated in the following equations in terms of V, which stands for the voltage difference, I, which stands for the current in amperes, and R, which stands for the resistance in ohms.
V = I X R
I = V/R
R=V/I
