Electronics Flashcards
1
Q
Relay definition
A
Acts as a link between so that a lower voltage circuit can control a higher voltage circuit.
2
Q
Why is using a microcontroller preferable to building a prototype?
A
Cheaper, because they do not require physical components.
Easier to fix mistakes because no real components.
Real, expensive components will not be damaged if a a mistake is made.
3
Q
Why do solar panels help combat climate change?
A
They reduce the need for power produced from fossil fuels, therefore reduce the amount of CO2 produced.
4
Q
What is the purpose of a diode?
A
To protect the transistor
5
Q
