1. Practice Problems to become familiar with circuits and circuit diagrams

2. Resistors The Breadboard Practice ProblemIdentify the various components in this breadboard circuit. + - 5 volts0 volts Resistors Light emitting diodes AND Logic Devices (7408) Light emitting diodes Digital component Dip Switches (8 separate switches in the set) Resistors

3. The Breadboard Practice ProblemDraw the circuit diagram for the breadboard circuit presented below. + - 5 volts0 volts

4. The Breadboard Practice Problem + - 5 volts0 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.

5. The Breadboard Practice Problem + - 5 volts0 volts + - LED A B Switch “A” has two positions Open Closed Switch “B” has two positions Open Closed Both switches are shown above in the open position Draw the circuit diagram for the circuit on Green side of breadboard

6. The Breadboard Practice Problem + - 5 volts0 volts + - LED A B Switch “A” has two positions Open Closed Switch “B” has two positions Open Closed 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?
