Introduction To Electronics

Intro. to Intro.
Electronics would not exist without resistance . One of the basic ways to change electrical current is to reduce it through resistance. Conductors are materials that allow currents to flow.
Isolator does not allow current to flow. Good conductors include the metals, copper, aluminium and carbon.
Vocabulary
Resistance- the inverse quantity of electrical conductors
Thomas Edison- an inventor and businessman; developed the "DC" of AC/DC
Nikola Tesla- the inventor of the "AC" of AC/DC
Circuit- made of electronic components like resistors, transistors, capacitors, inductors, and diodes connected by conductive wires or traces through electric current
Transistor- used to switch electronic signals and electrical power
Capacitor- stores energy in an electrical field
inductors-a component in an electric or electronic circuit that possesses inductance
inductance-the property of an electric conductor or circuit that causes an electromotive force to be generated by change in the current flowing
Electrical Charges
Electrical charges are a property of matter. Sub-atomic particles either have a positive or negative charge, anything else is considered neutral. The most common charges are electrons and protons. Atoms with more electrons than protons are called negative ions, and those missing electrons are called positive ions.
AC/DC
A direct current is an electric current flowing in one direction only.
Ohm's Law
V=IR
The "V" is the voltage, apparently the "I" is the current, and the "R" is resistance
A current through a conductor between is directly proportional to the potiental difference across the two points.
