Basic Electricity

Definitions:

• Resistance (R): The opposition offered by a material to the flow of electric current. It measures how much a material resists the flow of electrons.
• Conductance (G): The ease with which electric current flows through a material. It measures how easily electricity passes through a material.

Mathematical Relationship:

$ G S R \Omega \Omega S \Omega S \mho R = \frac{V}{I} G = \frac{I}{V} R = \rho \frac{L}{A} G = \sigma \frac{A}{L}$
