lesson 2 Flashcards
simulations are not real, they are designed to …
imitate the effects of what would happen if the experiment was conducted in the real world
tell me about simulations
COST EFFECTIVE
they are used as a cost-effective approach to designing and testing different prototypes.
CAN BE EDITED FREELY
Simulations can be edited freely until the best prototype is identified, then only one prototype needs to be built for final testing.
SAFE PLACE FOR TESTING
Simulations also provide a safe place for testing since the user can not be harmed like in real experiments where faulty prototype components can easily break, possibly causing harm to the user.
Due to these advantages, simulation is a safe and cost-effective way to explore new ideas and learn concepts.
Tinkercad is a …
simulating tool used to study the basics of circuitry and coding
A circuit can be described as a
closed, continuous loop that electrons can travel in.
All components in a circuit are connected to each other.
Current always flows from the …
negative (-) terminal of the battery, through the circuit components in the loop,to the positive (+) terminal.

Light Emitting Diode
Emits light when it receives electrons from the battery
The positive pin(anode) is longer than the negative pin(cathode) and the pins allow the LED to light up if current is received from the positive terminal of the battery
