Term
|
Definition
|

Term
What components are needed to make a complete circuit? |
|
Definition
A circuit needs a source of electricity (the D-cell), the receiver (the bulb) and a path to get from one to the other (wires) |
|
|
Term
What is important to remember about making a complete circuit? |
|
Definition
The electricity must be able to travel in a complete path (circle) from one end of the battery to the other |
