To allow electricity to flow easily
To control the circuit
To store energy
Which of the following is an example of a load in a circuit?
Wire
Battery
Light bulb
Switch
What does a switch do in an electronic circuit?
Provides power
Regulates or directs electricity
Produces sound
Stores energy
In a series circuit, what happens if one component fails?
Only that component stops working
The entire circuit stops working
The voltage increases
The current reverses
Which type of circuit allows other components to work even if one fails?
Series circuit
Parallel circuit
Closed circuit
Open circuit
Which of the following is NOT a basic component needed for every electronic circuit?
Power source
Load
Conductor
Insulator
If you want to build a simple flashlight, which components do you need to connect in a closed loop?
Battery, wires, light bulb
Battery, resistor, capacitor
Switch, speaker, solar cell
Motor, wires, switch
Why might a night light use a sensor to turn on automatically in the dark?
To save energy when light is not needed
To make the circuit more complex
To increase brightness
To reduce the number of components
If you are designing a musical greeting card, which component would you most likely include to produce sound?
LED
Speaker
Switch
Battery
A solar-powered battery charger uses solar cells as its power source. What is the main advantage of using solar cells in this project?
They are cheaper than batteries
They provide renewable energy
They increase the circuit’s resistance
They make the circuit more complicated
You are making a game with buttons and lights. What role do the buttons play in the circuit?
Power source
Load
Control element
Conductor
Imagine you have a string of old-fashioned Christmas lights wired in series. If one bulb burns out, what reasoning explains why all the lights go out?
The circuit is open, so current cannot flow
The voltage increases across the remaining bulbs
The bulbs are connected in parallel
The power source is disconnected
You are planning a house wiring system. Why would you choose a parallel circuit arrangement for the lights?
So that if one light fails, the others remain on
To reduce the total current in the circuit
To make installation easier
To increase the brightness of each light
Suppose you want to design a night light that turns on automatically in the dark. What components and arrangement would you use to achieve this, and why?
Use a battery, LED, and a light sensor in a closed loop so the LED turns on when the sensor detects darkness
Use a battery, LED, and a switch that must be pressed manually
Use a solar cell, LED, and a resistor in series
Use a battery, speaker, and a button
