The Breadboard
Practice Problem
+ -5 volts 0 volts
There are actually 2 separate circuits on this breadboard.
One is on the green side of the breadboard.
The other is on the blue side of the breadboard.
Let’s do the green side circuit first
Draw the circuit diagram for the breadboard c circuit presented below.

Is the light on or off right now?
Is the light on or off if switch “A” is closed?
Is the light on or off if switch “A” is open but switch “B” is closed?
Sorry no answers provided yet, you should work this out yourself.
For now, push on to the blue circuit.
Is there a unique combination of switch settings for the light to be on?
