Electonics

-Electric charge: fundamental conserved property of some subatomic particles, which determines their electromagnetic interaction.
-Electronic circuit: composed of individual electronic components, such as resistors, transistors, capacitors, inductors, and diodes, connected by conductive wires or traces through which electrical current can flow
-Voltage: Electrical potential difference. Is the electrical driving force that would drive an electric current between those points. Specifically, voltage is equal to energy per unit charge.
-Power: Rate at which work is performed or energy is converted.
-Types of voltage sources:
AC: Electric current that reverses direction sinusoidally; "In the US most household current is AC at 60 cycles per second"
DC: Symbol for the decicoulomb, an SI unit of electric charge equal to 10 coulombs
-Protoboard: construction base for a one-of-a-kind electronic circuit, a prototype.
-Ohm’s Law: Electric current is directly proportional to voltage and inversely proportional to resistance; I = E/R
