Circuit Components
T/F: A circuit utilizing an LED can be safely made without a resistor.
False
What are the blue and red lines on the breadboard called?
Power Rails
What is the power formula?
P = IV or P = I^2R
What is Soldering?
Joining two pieces of metal together using solder.
What are PCBs made of?
An insulating fiberglass/expoxy resin material
What is the purpose of resistors?
To limit the amount of current flowing through the circuit
What are the purpose of Breadboards?
They serve the purpose of allowing one to construct a circuit without permanent connections.
How can you tell what the resistance of a resistor is?
By decoding the colored bands wrapped around it.
T/F: You should blow on the soldered joint to cool it
False.
How are components attached to a PCB board?
Through soldering.
What is the numerical unit for electrical current?
Amps (A)
Black
What is this connection called when two components share two nodes?
Parallel
What is Flux used for?
Flux is a chemical agent used in soldering to clean metal surfaces, improve solder flow, and ensure a strong, reliable joint
What are some pros to using PCBs (List 3)?
-Reliable
-Compact
-Easy to design
-Easy to mass produce
-Easy to implement into various tech
What is the longer leg of an LED called?
What's the difference between a Strip Board and a Breadboard?
Strip boards are fiberglass boards with copper strips across it. Components can only be soldered onto it.
Breadboards are a plastic casing covering metal strips with metal clips. Components can be removed by hand.
What is Ohm's Law (formula)?
What is V/(I*R)
T/F: The flux is the part of the soldering process that is potentially harmful if inhaled in excess.
True
T/F: Multi-layer boards allow for more complex circuits without wires crossing
True
What two metals are usually used in Soldering coils?
Tin and Lead
What is the purpose of the DIP (The straight line down the middle of the BB)
Dual in-line Package (DIP) Support: allows the different legs of circuit elements with multiple functions to remain isolated from each other
What is the difference between a series and parallel connection?
Series: Two components share one node
Parallel: Two components share two nodes
Is soldering the same as welding?
What devices are PCBs used in (List 3)?
-Appliances
-Computers, TV, Phones
-Wifi Routers
-Communication Systems
-Automotive Systems
