Circuits+2

-Voltage: Electromotive force. -Current: A flow of electricity through a conductor. -Resistance: A property of a conductor by virtue of which the passage of current is opposed, causing electric energy to turn into heat energy. -Circuit: An electrical device that provides a path for electrrical current to flow. -Transistors: A semiconductor device that amplifies, oscillates, or switches the flow of current between two termenals by varying the current or voltage between one of the terminals and the third. -LEDs: A light-emitting diode is a semi conductor light source. - Capacitor: A device used to store an eletric charge. -Resistor: A device having resistance to the passage of an electric current. -Switch: A device making or breaking the connection in an electric circuit. -Digital Electronics: The implementation of two-valued logic using logic gates such as and gates, or gates and flip- flops. -Integrated Circuit: A circuit of transistors, resistors, and capacitors constructed on a single semiconductor wafer or chip, in which the components are interconnected to perform a given function. -Binary Code: A system of representing letters, numbers, or other characters, using binary notation. -Circuit Breaker: A device for interupting an elecric circuit to prevent excessive current, as that caused by a short circuit, from damaging the apparatus in the circuit or from causing a fire. -Conductor: A substance that conducts electricity.

1.Integrated Circuit a. Contains hundreds of parts. b. A complex set of electronic components that are on a tiny slice of semiconducting material. 2. Circuit Breaker a. Protects houses, school, and all building with electricity from an electrical overload. 3. Conductor a. Carries electricity 4. Reciprocating a. A back and forth, or up and down motion which repeats over and over again. 5. Rotary Motiona a. Motion that goes in a circle. 6. Oscillating Motion a. Motion that moves along a path then return along the same path.
