|
|
What is a circuit breaker?
|
A reuseable safety switch that breaks the current when the current gets too high.
|
|

|
|
If oyu remove a bulb in a series circuit, will the rest go out? Why?
|
The rest of the lights will go out because there is a break in the current.
|
|
|
If you remove a bulb in a parallel circuit, will hte other bulbs go out? Why?
|
They will not go out becuase there i s more than one path ofr the current ot take
|
|
|
What is induction?
