The basic law that most people are familiar with is Ohm's Law which relates the voltage, current, and resistance of a circuit by:
V = IR (some people use E instead of V).
However, there are a number of laws and equations that describe the behavior of electricity and electromagnetism. One set of equations which summarizes many of the individual observations and equations of Gauss, Faraday, Ampere, and others is known as Maxwell's Equations. These are very "beautiful" mathematical equations that are not necessarily easy to apply in everyday usage, but they form a foundation for things like fiber optics, cell phone communications, etc.

Ohm's Law States:
Current in a circuit is directly proportional to voltage and inversely proportional to the resistance.
I = E/R
Where I = current in amperes
E = Electro Motive Force (Voltage)
R = Resistance in ohms

properties of electric charge, a fundamental property of the universe electric charges what ever they "really are" come in two kinds, called positive and negative, just words we could call them blue and Wednesday if we liked if two charges are the same kind they repel, if they are different they attract they change space around them to exert force on each other all the rest is just details, that take about 2 years of physics study to begin to understand

V = IR is the basic "law".
Voltage equals Current x Resistance.
It applies to direct current.
The equivalent for AC is:
V = IZ (Z= impedance)

Uhm.. There are quite a few.
Most useful one in circuits:
V = IR (voltage = current times resistance)
Most useful (simplified) one in physics:
V = E*D (voltage = electric field * distance)
