Short terms
What does Dc and Ac stand for?
Dc stands for = Directing current
Ac stands for = Alternating current
Resistors
Impede the flow of current in a circuit
What does electric potential actually measure?
Voltage or strength
How does current in 1 device compare to the current in other devices that are in series?
Explain how your programing language uses comments
aposterphe ‘
What are m,k and M prefixes
m = /1000
k = *100
M = *1000000
Capacitors
Store electrical energy
What does voltage actually measure? What about current?
- the potential difference between 2 electrically connected points
- the rate at which charges are moving through a circuit
What subatomic particles make up the charges in electricity? What are their charges?
- proton = positive +
- electron = negative -
What does BOE stand for? What does the reset button do?
Board of education
Reset the microcontroller
What units do we measure current, voltage, resistanc?
I
volts
R
Transistors
Amplify or switch electronic signals
What is resistance
a measure of how much a component opposes the electric current moving through it
Explain how losing electrons changes your overall charge. Why is electricity made of electrons?
Results in a positive charge because electrons are negatively charged the primary charge carries
What does DEBUG do? What is the DEBUG terminal?
Print messages on the computer screen
the blue window
What does conventional current flow from a battery? What about Electrons?
Positive to negative
Negative positive
Transformers
Transfer electrical energy
What is Ohms law?
less resistance means more current
What is an LED and how is it different from a diode?
Led emits lights unlike a regular diode
What characters did we learn about in the first chapter of robotics? What do they do?
CR allows to go to the next line
How do particles attract and repel?
Like charges repel
Opposite charges attract
What is a parallel circuit? Series circuit?
- Parellel circuits have 2 or more components connected in parellel
- Series circuits have 1 single pathway for current to travel through
What are differences between an open and a closed circuit? In which one can current exist?
an open circuit has a break preventing current flow closed has a complete path
Explain how adding more pathways for electricity affects the resistance. Use real life example also.
- adding more pathways decreases resistance
- highways vs single lane roads
