Circuit builder Click on the link above.

Make a series circuit and screenshot it.

Include a light bulb and a switch in the circuit and make 3 observations of how you built the circuit.

1.

2.

3.

Put the screenshot of a series circuit here.

4 pts

Series Circuit 1. What happens to the circuit when the switch is opened?

2. What happens to the circuit when the switch is closed?

3. Use the voltmeter and determine how many volts are traveling through the circuit.

4. Add another light bulb to the circuit. How does the voltage change between the light bulbs?

5. Does the overall voltage of the circuit change?

6. Put an ammeter in the circuit, what is the ampage of the circuit?

7. Does the ampage change throughout the circuit?

7 pts

Parallel Circuit Make a parallel circuit include two light bulbs and a switch.

Screenshot the parallel circuit and put below.

Make 3 observations of how you built the circuit.

1.

2.

3.

Put screenshot of parallel circuit here.

4 pts

Parallel Circuit 1. Use the voltmeter and find the voltage of the circuit.

2. Using the ammeter, how many amps are there in the circuit?

3. Add another light bulb to the circuit in the same line as one of the other light bulbs. Does this change the voltage between the two bulbs?

4. What is the voltage for one bulb?

5. What is the voltage for both bulbs in the same line?

6. Did the ampage of the entire circuit change? Why or why not?

Why Current Flows

• Watch this animation and explain in a couple sentences

• 1. How current moves

• 2. Why copper is such a good conductor of electricity.

• HINT: Copper has a +2 charge… meaning for every atom of copper it attracts 2 e- to be neutral. Also use start stop and ff buttons at the bottom

5 pts

Current Flow

• 1. What effect does voltage have on current strength

• 2. What other real life thing can you compare voltage and current to…. Explain the analogy

• 3. Current is the flow of ________, and flows from ________ to __________...

• 4. Use the applet to explain why most diagrams show current moving from positive to negative
