Electric Circuits Basics: 15 flashcards
All 15 flashcards from this kit, free and with no sign-up.
1. What is the function of an electric switch in a circuit?
Show the answer
A switch is a simple device that either completes or breaks a circuit, allowing or preventing current flow.
2. In the homemade switch from Activity 3.8, which two items act as the terminals?
Show the answer
Two drawing pins act as the terminals; the safety pin connects them.
3. What is the ON position of a switch?
Show the answer
When the switch closes the gap and completes the path, allowing current to flow. The circuit is closed.
4. What is the OFF position of a switch?
Show the answer
When the switch leaves a gap in the circuit, preventing current flow. The circuit is open.
5. In the symbol for an electric cell, what does the long line represent?
Show the answer
The positive terminal.
6. In the symbol for an electric cell, what does the short line represent?
Show the answer
The negative terminal.
7. Can a switch be placed anywhere in a circuit?
Show the answer
Yes, a switch can be placed anywhere in a circuit.
8. What happens to the lamp when the safety pin touches both drawing pins?
Show the answer
The lamp glows because the circuit is closed and current flows.
9. What happens to the lamp when the safety pin does not touch the second drawing pin?
Show the answer
The lamp does not glow because the circuit is open and current cannot flow.
10. What is the purpose of using symbols in circuit diagrams?
Show the answer
Symbols represent electrical components in a simpler manner, making diagrams easier to draw and understand.
11. List the components that have symbols in Table 3.2.
Show the answer
Electric cell, battery, electric lamp, LED, switch in ON position, switch in OFF position, and wire.
12. What does a closed circuit mean?
Show the answer
A closed circuit is a complete path that allows current to flow, like when a switch is in the ON position.
13. What does an open circuit mean?
Show the answer
An open circuit has a gap that prevents current flow, like when a switch is in the OFF position.
14. In Activity 3.9, what is the purpose of connecting the electric cell, lamp, and switch?
Show the answer
To test the switch and observe how it controls the lamp's glow.
15. How does a switch turn on or off a torchlight?
Show the answer
The switch completes or breaks the circuit, allowing or stopping current flow to the lamp.
