Draw

Circle your prediction.

Multiple Choice

What is the value on your ammeter?

• 0.90 A

• 0.45 A

• 1.8 A

• 0.30 A

Multiple Choice

So, we added another bulb in series and the current went down from 0.9A to 0.45A. What did Ohm have to do to Amp to slow him down?

• Pull tighter to increase the resistance.

• Let loose a little to reduce the resistance.

Multiple Choice

To summarize, in a series circuit, when more bulbs are added, the "brightness"

• goes up.

• goes down.

Multiple Choice

To summarize, in a series circuit, when more bulbs are added, the "current"

• goes up.

• goes down.

Multiple Choice

To summarize, in a series circuit, when more bulbs are added, the "resistance"

• goes up.

• goes down.

Multiple Choice

Current and Resistance are ___ related.

• directly

• inversely

Multiple Choice

If you disconnect one of your bulbs in your series circuit, what happens to the rest of them?

• They all go out

• The other bulbs stay on

Draw

Think and predict, circle either increase or decrease.

Multiple Choice

What is the value on your ammeter?

• 0.90 A

• 0.45 A

• 1.8 A

• 0.30 A

Multiple Choice

To summarize, in a parallel circuit, when more bulbs are added, the total "current"

• goes up.

• goes down.

Multiple Choice

To summarize, in a parallel circuit, when more bulbs are added, the total "resistance"

• goes up.

• goes down.

Multiple Choice

If you disconnect one of your bulbs in your parallel circuit, what happens to the rest of them?

• They all go out

• The other bulbs stay on

Multiple Choice

So, we added another bulb in parallel and the current went up. What did Ohm have to do to Amp so he could flow faster?

• Pull tighter to increase the resistance.

• Let loose a little to reduce the resistance.

Multiple Choice

Current and Resistance are ___ related.

• directly

• inversely

Audio Response

Now for you to practice! Add a third bulb in either series or parallel.

Then, on the mic, describe your circuit and tell me how the current and resistance changed!
