Capacitors I

What is the main function of a capacitor as described in the video?

• To produce new electrons

• To store electrical energy

• To convert electrical energy to mechanical energy
  

• To create a circuit

How do electrons move in a circuit according to the video?

• From negative to positive
  

• In a circular motion

• From positive to negative
  

• They do not move

  
  

What keeps the plates inside a capacitor from touching each other?

• A conductor

• A resistor

• The battery

• The dielectric

What is the role of the battery in the charging process of the capacitor?

• Starting motors in vehicles
  

• Powering electric cars
  

• Storing solar energy

• Running household appliances

When does the capacitor stop charging?

• When the switch is opened

• When it loses charge

• When it reaches the voltage of the battery
  

• When it cools down

What happens to the electrons on the capacitor’s negative terminal when it discharges?

• They remain stationary
  

• They are absorbed by the positive terminal
  

• They move toward the positive terminal
  

• They flow into the ground

  
  

Which of the following devices can benefit from a capacitor's quick discharge capability?

• light bulbs

• electric motors

• flash bulbs in cameras

• batteries
