What does "RC" in an RC circuit stand for?

• Resistor and Current

• Relay and Conductor

• . Resistor and Capacitor

• Resistance Control

What is the main function of a resistor in an RC circuit?

• Store energy

• Speed up the charging process

• .Control the flow of electric current

• Light up the LED

What does a capacitor do in a circuit?

• Controls voltage
  

• .Stores electrical energy

• Removes noise

• Increases temperature

Charging a capacitor is like:

• Water falling off a roof

• .Filling a tank slowly through a narrow pipe

• .Turning a fan on and off

• Heating water in a kettle
  

Discharging a capacitor is like:

• . Turning on a slow light

• Gradually using battery power

• Letting all the water out of a tank at once

• Dripping water from a tap

True or False: The capacitor in a flashlight charges instantly.

• True

• .false

What causes the bright flash in a flashlight device?

• A resistor heating up

• A fast battery charge

• . A quick capacitor discharge

• A rotating motor

Which part of the circuit controls how fast the capacitor charges?

• .Switch

• LED

• Battery

• Resistor

True or False: RC circuits are used only in flashlights.

• True

• .False

Which of the following is a safe design tip when building your own flashlight circuit?

• Skip checking component ratings

• Test directly on the final circuit

• Always use a breadboard first

• .Use random parts from old electronics
