course PHY 232

2:00 pm 4/29 Skipped through a couple that wasn't lab related just crunching the numbers and takes more time to type up than to work through.

Lab Activities from 03/28Pictures are not included.

Additional questions.

The leads from the generator are sort of silver-colored.  They run out of the generator, and appear again at the bottom of the picture, where they are connected to the red and black leads.

Assume that, when the meter is cranked counterclockwise, the generator lead connected to the red lead is positive and the generator lead connected to the black lead is negative.

Trace the current from the generator through the circuit and back to the generator.

Question:

`q002.  Trace the current in this circuit. 

Your solution

Does current pass through both bulbs?

****

#$&*

If one bulb was disconnected, would current still flow?

****

#$&*

Is there a direct connection between the first bulb and the generator?  A direct connection is one in which you can get from one side of the bulb to one terminal of the generator without passing through anything but conducting wire (e.g., without passing through another bulb or other circuit element), and from the opposite side of the bulb to the opposite terminal of the generator, again without passing through anything but wire.

****

#$&*

Is there a direct connection between the second bulb and the generator?

****

#$&*

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

Yes through both but can't be disconnected and neither have a direct connection.

Question:

`q004.  Now there's a meter in the circuit.  The red lead of the meter is connected to the 'red' side of the bulb, the black lead to the 'black' side.

Does the meter have a direct connection to the generator?

****

#$&*

How many possible paths can the current take through the circuit?

****

#$&*

If the leads of the meter are removed, will current still flow through the bulb?

****

#$&*

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: 

The meter does have a direct path and there are 3 paths and current would still flow.

Does the meter have a direct connection to the generator?

****

#$&*

If the leads of the meter are removed, will current still flow through both bulbs?

****

#$&*

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: 

Doesn't look like red and white leads are together. Looks like the meter is across the bulb where the bulbs are in series now and current would still flow if one is removed.

#$&*

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: 

 Bulb has direct connection and capacitor does sort of, that yellow wire is shorting it out and it probably won't have any I. If white lead is removed then I will still flow through bulb and 'short' across the cap. green lead has no effect on bulb here.

If the red is detached from the bulb, will current flow?

****

#$&*

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:  

 Bulb is direct but cap is not to gen and only cap is direct to battery but not to both sides of it so that doesn't exactly work. I will flow thru bulb if white lead is moved and the bulb might work bc of the battery but I think it's going to short.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: 

 bulb is still direct to gen but cap still doesn't bc of the battery. Bulb still isn't direct to battery and neither is cap. I will flow thru bulb if white is removed and the battery may power the circuit if red is removed but I think these 'short' connections would keep that from happening.

Your solution: 

 bulb is still direct but cap is not and bulb not to battery and cap not either. I will not flow thru cap if white is removed and I still don't think so if the red is removed.
