Total questions: 11
Worksheet time: 6mins
What is the primary function of copper tape in your light-up bracelet project?
To insulate electrical components
To conduct electricity between components
To provide structural support
To decorate the bracelet
What does LED brightness depend on?
The shape of the bracelet
The color of the copper tape
The strength of the battery
The size of the circuit
Which component supplies power to the LED in the bracelet?
Resistor
Switch
Coin cell battery
Capacitor
Why is it important to connect the LED correctly in the circuit?
LEDs are non-polarized components
LEDs will only light up if connected with correct polarity
Incorrect connection will make the LED change color
It doesn't matter how LEDs are connected
What could be the reason if the LED does not light up after assembling the bracelet?
The battery is inserted upside down
The copper tape is not conducting electricity
The LED is connected in reverse
All of the above
What is the role of the insulating layer in the bracelet design?
To prevent short circuits by separating conductive paths
To enhance the bracelet's appearance
To increase electrical conductivity
To store electrical energy
Which material are commonly used as a conductor in e-textile projects?
Plastic thread
Rubber bands
Conductive fabric tape or Copper tape
Nylon strings
What is a common voltage rating for coin cell batteries used in light-up bracelets?
1.5V
3V
5V
9V
How can you test if the copper tape connections are working properly in your bracelet?
Visually inspecting the tape
Using a multimeter to check continuity
Measuring the length of the tape
Checking the color of the tape
Which part of the engineering design process are you using when your LED doesn’t light up and you adjust the copper tape to fix the connection?
Brainstorm
Redesign (Improve)
Research
Communicate
Why is conductive fabric tape especially useful in wearable technology projects like the light-up bracelet?
It is stretchy and purely decorative
It blocks the flow of electricity to protect components
It allows electricity to flow while being flexible and comfortable to wear
It reflects light to make the LED appear brighter
