When an input to a logic chip has no connection to positive or negative, the logic gate will freak out. That condition, not being connected is called:

• Pulling Down

• Drifting

• Floating

• Lifting

Logic gate circuits require lots of positive and negative connections. The thing they connect to is called a...

• Breaker

• Shuttle

• Bus

• Array

The left side is connected to

• 5V Positive

• The "ground" negative

• An electric Jelly fish

• A ray

Which situation would make the most sense to use an AND gate?

• Sound the alarm if smoke it detected. Sound the alarm if the manual lever is pulled. Sound the alarm if both happen.

• The missile should launch when both buttons are pushed.

• The night light should turn on when the regular lights are OFF (no light detected).

• Do not turn on the sprinklers it rained today or there is a football game today.

Which situation would make the most sense to use an NOR gate?

• Sound the alarm if smoke it detected. Sound the alarm if the manual lever is pulled. Sound the alarm if both happen.

• The missile should launch when both buttons are pushed.

• The night light should turn on when the regular lights are OFF (no light detected).

• Do not turn on the sprinklers it rained today or there is a football game today.

Which situation would make the most sense to use an NOT gate?

• Sound the alarm if smoke it detected. Sound the alarm if the manual lever is pulled. Sound the alarm if both happen.
