MIDTERMS - LESSON 2 Flashcards
______ or the _______may be presented
using words, pictures, or diagrams.
Circuitry
system of circuits
A ______ is a graphic representation of an
electric circuit.
circuit diagram
circuit diagram is also called as:
● electrical diagram
● elementary diagram
● electronic diagram
It refers to the system of components, power, and signal
sources that enable the current to flow around.
Circuit
● implies that the circuit is
complete
● current can freely go
around
Closed Circuit
● implies that the circuit is
incomplete
● there is a gap somewhere
in the path
Open Circuit
this is a component of a circuit diagram: connected to an
electric power supply
BULB
this is a component of a circuit diagram: device that generates
electricity
Cell (DC voltage
source)
this is a component of a circuit diagram: composed of two or
more cells
Battery (DC voltage source
this is a component of a circuit diagram: allows current to flow
Connecting wire
this is a component of a circuit diagram: controls the flow of
electric current
Resistor
this is a component of a circuit diagram: two-terminal electrical component for energy storage
Capacitor
this is a component of a circuit diagram: allows electric current
to flow in one direction while stopping it in the other direction
Diode
this is a component of a circuit diagram: amplifies/switches
electronic signals and power
Transistor
this is a component of a circuit diagram: resists AC while
permitting DC to pass
Inductor
this is a component of a circuit diagram: trades voltage for
current or vice versa
Transformer
this is a component of a circuit diagram: turns the flow of
electricity on or off
Switch
this is a component of a circuit diagram: device used to
measure current
Ammeter
this is a component of a circuit diagram: device used to
measure potential difference
Voltmeter
