Circuit symbols Flashcards
A somewhat list of circuit symbols in word form type shi
Ig their functions here too
Okay
Okay
Dot line and dot
component?
Connecting lead
Function:
to connect the component to a circuit or another component
What does a cell look like?
Longer line one side
Shorter line other side
Function:
Provide emf to the circuit
When there’s 2 cells
component?
Battery of cells
Function:
Probably even more emf to the circuit
A rectangle
component?
Fixed resistor
Function:
Control or limit flow of electrical current
Has a set resistance value
Dot and dot with no line in-between
component?
Power supply
Function:
Well apparently it’s just like a cell but it’s just anything that provides power soooo, ye?
3 way line with dot in middle
component?
Junction of conductors
Function:
It’s rlly not well said in the websites sooo
I mean it’s where the electricity is branched off ig?
4 way line
component?
Crossing conductors (no connection)
Function:
Just like junction man, what da hell
S’pose no electricity idk?
Circle with x within
component?
Lamp
Function:
Provide illumination
Used as an indicator
Circle with v within
component?
Voltmeter
Function:
Measure voltage
either circuit or component
Circle with A within
component?
Ammeter
Function:
Measure current
either circuit or component
Dot, line going up from one, dot
component?
Switch
Function:
To make or break the electric circuit
Rectangle with diagonal arrow
component?
Variable resistor
Function:
Control or limit flow of electrical current
Resistance can be changed manually
Circle with 2 lines ig? (diep.io)
component?
Microphone
Function:
Convert sound waves into electrical signals
Volume button connected to 2 lines from rear
component?
Loudspeaker
Function:
Converts electrical audio signal into a corresponding sound
Rectangle but the line goes thru it
component?
Fuse
Function:
breaks the circuit if a fault in an appliance causes too much current to flow
Line with pyramid below it
component?
Earth
Function:
Provide protection from electric shocks
Circle with ~ within
component?
Alternating signal
Function:
Interesting, DC is when current flows in one direction
AC is when current flows forwards and backwards
Both lines vertical are bold and same size
component?
Capacitor
Function:
temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference
lol i copied it
Square but it’s a diagonal line with a rear horizontal below
component?
Thermistor
Function:
Temperature sensors
Changes resistance based on temperature
Circle with rectangle within and 2 arrows from top left pointing at it
component?
light-dependent resistor (LDR)
Function:
Detect light levels
Changes resistance based on light intensity
Circle but line goes thru and it’s a triangle and line within
component?
Diode
Function:
Allow electric current to pass in one direction specifically
And blocks it in the opposite direction
Circle but line goes thru and it’s a triangle and line within AND 2 arrows pointing outwards
component?
light-emitting diode (LED)
Function:
Convert electrical energy directly into light
