Mechanisms Using Electricity

What are the categories of electrical use?

• heating

  lighting

  communicating

  moving

• crawling

  flying

  digging

  climbing

• eating

  burping

  scratching

  running

What is a series circuit?

• a circuit in which there is more than one pathway for electricity to flow.

• a circuit in which there is only one pathway for electricity to flow.

What is a parallel circuit?

• A circuit in which there is more 

  than one pathway for electricity

  to flow. 

• A circuit in which there is only one 

  pathway for electricity to flow 

  
  

What is a circuit breaker?

• 
  

  e. A form of energy resulting from

  The movement or build up of  charged particles (protons and 

  electrons)

• A device used in a circuit in which

  The wire will melt if there is too 

  much current flowing, thus 

  breaking the circuit and stopping 

  the flow of electricity. 

• An automated switch that turns off a circuit if there is too much 

  current flowing or short circuit 

  occurs. 

What is a fuse?

• An automated switch that turns off a circuit if there is too much 

  current flowing or short circuit 

  occurs. 

• A device used in a circuit in which the wire will melt if there is too much current flowing, thus breaking the circuit and stopping the flow of electricity.

• a machine that supplies or produces motion.

What is a switch in a circuit?

• An automated switch that turns off a circuit if there is too much 

  current flowing or short circuit 

  occurs. 

• something used to turn electrical circuits on or off

• a machine that supplies or produces motion

In a series circuit with two lightbulbs, if one lightbulb burns out, what will happen to the other lightbulb?

• It will stay on

• It will not light because it will burn out too

• It will not light because the pathway has been broken

• It will light brighter than before

In a parallel circuit with two lightbulbs, if one lightbulb burns out what will happen to the other lightbulb?

• It will not light because it will burn out too

• It will stay on

• It will not light because the pathway has been broken

• It will light up brighter than before.

"Blowing a fuse" means:

• a fire starting in a circuit

• a switch automatically turning an circuit off

• using too many pathways in a circuit

• a wire melting due to too much current flowing

How are circuit breakers and fuses the same?

• They both protect electrical circuits from overloads and short circuits.
• They are only used in outdoor settings
• They are used for heating purposes
• They are made of plastic material
