Question	Answer
...	Xor gate, Multiplexer
a component that supplies and controls energy.	Active components
typical visual representation of a system that displays the input and output through blocks joined by lines.	Block diagram
represents the major part or function in a system	Box
this symbol connects the boxes in a system to illustrate relationships.	Line
this figure is specifically used to indicate the flow of the signal or data through the electrical block diagram and software design	Arrow line
graphical representation of a functional process via blocks and diagrams that is easier for a reader to understand and interpret.	Functional Block Diagram
diagrammatic representation of sequence of logical steps of a program.	Flowchart
electrical component that restricts the flow of current in the circuit.	resistor
is a two-terminal linear passive component that is made from two conductive plates with an insulator between them. it stores electrical energy	capacitor
is a small computer on a single integrated circuit that assembles all the features that are found in the microprocessor. used in various automatically controlled devices such as remote controls, medical devices, automobile engine control systems, power tools, toys, office machines, and other embedded systems.	microcontroller
a reactor is a two-terminal passive electrical component. it stores electrical energy in the form of magnetic energy.	inductor
electrical device that consists of two coils of wire, that are linked by an iron core. The main function of it is to increase (step-up) or decrease(step-down) AC voltages.	transformer
an electrical device that is used to convert chemical energy into electrical energy.	battery
a piece of wire which is used to protect the components from destruction due to the excessive current flowing through them.	fuse
a device which is made from a semiconductor material that allows current to flow in one direction; it blocks the current which tries to go against the flow in a wire.	diode
consists of three terminals, made of semiconductor material that controls the flow of voltage or current and acts as a switch for electronic signals.	Transistor
a semiconductor device, where loads of resistors, capacitors, and transistors are fabricated. It can function as an oscillator, microprocessor, amplifier, and timer. also called a microchip.	integrated circuit
electromechanical switches that are used to control the circuits by using a low power signal.	Relays
an electrical device that is used to break the circuit, interrupting the current and to supply the current from one conductor to another conductor.	switch
(SPST)	single pole single throw
(SPDT)	single pole double throw
(DPST)	double pole single throw
(DPDT)	double pole double throw
an electrical device and the main function of the motor is to convert electrical energy into mechanical energy.	motor
a mechanical switching device which is operated automatically and is used to protect the electrical circuit from the damage caused by overload or short circuit.	circuit breaker
a component which response to the flow of electrical energy and either dissipates or store energy.	Passive components
