Note: Because there is so much overlap between the lessons in this unit, I’ve combined all the questions from Lessons 1-3 and put them all in one place – right here on this page.
Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

- Name two different types of power supplies that you can use.
- If I have a 24 volt light bulb that uses 3 amps, what would happen if I hooked it up to a 1-amp power supply? 1000-amp power supply?
- What does a transformer do?
- I need a 5.6k-ohm resistor. What does the resistor color code look like?
- I need a 2k resistor, but I only have 1k resistors left in my bin. How do I connect them together to make a 2k resistor?
- Why bother using a capacitor in a circuit?
- I need a 400mf capacitor, but only have 200mf capacitors in my bin. How do I make a 400mf capacitor?
- Give examples of where you’d find AC and DC current in everyday life.
- What’s a diode and how do you know which way the electricity flows?
- What the difference between a microprocessor and microcontroller?
- What’s an IC?
- Can I substitute one transistor for another?
