Materials that block flow of electrons are called insulators (e.g., rubber, glass, Teflon, mica, etc.). Materials whose conductivity falls between those of conductors and insulators are called semiconductors.

What makes them move from atom to atom? What is Voltage? What is Current? What is Resistance? How do these three concepts relate to each other? What are conductors, what are insulators? Electricity Basics - some answers to the questions above: The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).

Basic Electronic Formulas for Devices
The S.I. unit of current is ampere and is denoted as A. One ampere current is said to flow through a conductor when a charge of 1 coulomb passes through any crossection in 1 second. 1 A = 1 C/ 1 s 1 mA = 10-3 A, 1 µA = 10-6 A In metals, the carriers of electric current are negatively charged electrons. As a matter of convention, the direction. Basic Electrical Formulas Volts (E): Volts = square root of (watts x ohms) Volts = watts / amperes Volts = amperes x ohms Ohms (R): Ohms = volts / amperes Ohms = volts2 / watts Ohms = watts / amperes2 Watts (W): Watts = volts2 / ohms Watts = amperes2 x ohms Watts = volts x amperes Amperes (I): Amps = volts / ohms Amps = watts / volts
