Resistance, Resistivity, Ohm's Law, Simple Electric Circuits - Physics

The meaning of resistivity (high or low) vs resistance and the difference between them is explained in simple words or terms. Ohm's law, formula, statement or equation is explained using the definition, the graph of current vs voltage, and an example of a simple circuit. It is used to calculate the voltage drop of an electrical load but is not universal and resistance has units of ohms (or volts on amps).
