In Activity 1.1.2 Investigating Basic Circuits you created a simple circuit similar to the one shown. What does that tell you about LEDs (a type of diode)?

• LEDs can only operate in one direction.

• LEDs can operate in both directions.

• LEDs do not require a power source.

• LEDs are not affected by circuit polarity.

What is the role of the resistor is in the circuit?

• To increase the current

• To decrease the voltage
