1. Three lightbulbs and a voltage source are connected in parallel with each other. One lightbulb is removed. What happens to the other two? Do they get brighter, dimmer, stay the same, go out?

2. Now the three bulbs are in series with the voltage source. What happens when one is removed?

3. Now, two are in series with each other, but this set is in parallel with the third and the battery. What happens to each of the other two when one of the series ones is removed?

1. The other two bulbs should remain the same brightness since the voltage difference across each bulb does not change and the resistance of each bulb doesn't change. Therefore, according to $P=\frac{V^2}{R}$ the power remains the same, which means the brightness must remain the same.
2. If all three bulbs are in series with each other, then if one is removed, the other two will go out since the circuit is now open.
3. If one of the series bulbs are removed, the bulb that was in series with the removed bulb will go out for the same reason in question 2. The one parallel to the series bulbs will remain on and at the same brightness for the same reason in question 1.

### Re: Circuit Lab B

I am in the bathtub while I am charging my phone. I see that it is fully charged, and I go to reach for the wall adapter. With my soapy hand, I have trouble pulling out the adapter, so I try to go behind it to give some leverage. To my demise, I touch the prongs while the adapter is still in the wall. Immediately following this, there was an audible pop.

a) What was the popping sound from, and why did the popping happen?
b) Am I alive or dead?

Electric Shock, possibly ESD can result from it; so you could be dead or alive. Hopefully alive if you regain consciousness. The popping sound was from a Ground-Fault Circuit Interrupter (GCFI) outlet. All bathrooms are supposed to have GFCI outlets according to the National Electrical Code. The electricity would most likely travel through your body to ground for a split second before the GFCI outlet pops. Hence, the popping is from the GFCI.

^^Reposted most recent question
I forgot about that since I don't use any of the plugs in my bathroom, and I haven't really studied that aspect of Circuit Lab, I guess that makes sense.

Anyhow nobody answered my last question.
