Alternating Current: Electrons move in one direction then star moving the opposite.
Ampere: a unit of electric current equal to a flow of one coulomb per second.
Diode: a tiny electronic device that acts as a one way value to allow electron flow in only one direction.
Direct Current: an electric current flowing in one direction only.
Electric Current: An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.
Electric Power: Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
Ohm: the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
Ohm's Law: the relationship among voltage, current, and resistance.
Potential Difference: the difference of electrical potential between two points.
Voltage Source: A Voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current.
