- An open circuit is a circuit is an electric circuit in which the normal path of current has been interrupted
- A closed circuit is an electric circuit providing an endless path for the flow of current.
- A short circuit is a circuit that is closed but does not have a source in which the energy can go to. That makes it so the battery dies faster and there is a possibility of damage.
SAFETY
- When using a COPING SAW to cut wood, make sure your saw is in line with your shoulder so that you can always make a straighter line.
- SAFETY GOGGLES should be worn at all times. Severe injury could occur if goggles are not worn at all times.
- HACK SAWS are meant to cut metal, and metal alone. When using a hack saw, like a coping saw, make sure your saw is aligned with your shoulder and your goggles are on. Also, hack saws are very easy to break so use them with care.
