a circuit where the current has only one path to
take
What is a series circuit?
100
Electrical energy brings 4 things that makes life easier for us. What are these 4 things?
What is heat, light, communication, and movement
100
a thin strip of metal that melts if a large electrical current goes through it
What does a fuse look like?
100
These are the 2 types of switches and their jobs are
What are network and light switches? Network switches link network devices and light switches turn on lights
200
This devices sends a message for another device to turn on or off
What is a switch?
200
a circuit where each bulb/battery is in its own
circuit
What is a parallel circuit?
200
This an example of heat that electricity gives us
What is a furnace?
200
This is how a fuse works
What is when the fuse melts the circuit is broken and the flow of electricity will stop. The fuse will have to be replaced but the appliance will not be damaged
200
What are the 5 functions of switches?
What is they work to control a variety of functions such as:
On/off, speed, brightness, volume and amount of heat?
300
this is used to prevent circuits from overloading
What is a circuit breaker?
300
devices that create a magnetic field through the
application of electricity
What is an electromagnet?
300
This is an example of communication that electricity gives us
What is a phone, fax machine, etc?
300
What are used instead of fuses in buildings?
What are circuit breakers?
300
This is the advantage and disadvantage of a fuse
What is advantage: cheap,prevents overload of electricity
disadvantage: use only one time
400
this switch controls two circuits
What is a double switch?
400
a safety device that prevents appliances from
being ruined when circuits are overloaded
What is a fuse?
400
This is an example of light that electricity gives us
What is a ceiling light, a lamp, night light, etc?
400
How does a breaker work?
What is a breaker is put into a household circuit. It will flip up and “break” the circuit if the current is too strong. This will happen if too many appliances are plugged into one socket at the same time
400
This is the advantage and disadvantage of a circuit
What is advantage: prevents overload of electricity , you can reuse it
disadvantage: expensive to replace
500
this switch controls a circuit from two
different points
What is a two-way switch?
500
These are different ways that electricity can be made
What are hydro,solar,air,fossil fuels?
500
This is an example of movement that electricity gives us
What is rc cars?
500
The difference between a fuse and a breaker is this
What is once some of the appliances have been unplugged, the breaker can be flipped back. With a fuse, though, a fuse must be replaced with a new one each time it burns out.
