I know you said be careful how I put that and I was trying to quote Mr Samurai and i did not quote him accurately. In his first video on series and parallel circuits about 3:23 into the video he says voltage by itself does nothing.

Thats all I was trying to do and say:)

I am a little nervous I haven’t attempted to retake this since you reset it. what are my options if i bomb again? I hope that’s not the case but i’m asking what if?

In the circuit with several bulbs in a row, remember: the current will be the same through the whole circuit. If those bulbs are identical, then each would have the same amount of voltage drop, and the sum of those voltage drops would equal the source voltage.

I was trying to take notes on the video. The test question reads “select the true statement about voltage in a series circuit”. so i re watched that particular segment and tried to find what I was missing CONCERNING VOLTAGE IN A SERIES CIRCUIT

This is what I understand:

-I understand voltage creates the potential for current to flow.
-voltage itself does nothing
-voltage drops depends on each load in the circuit.
-the sum of the voltage drops should be equal to the whatever the source voltage is

also:
-I also understand voltage is the same in each parallel branch of the circuit.
-In parallel circuits each branch is connected to the power supply
-if there is a break in one branch the total current will decrease
-The current is NOT necessarily the same but that it depends on the loads
-voltage is the same in each parallel branch
-The total current in the circuit will equal the sum of the current in each branch.

when it comes to VOLTAGE and CURRENT in these circuits I guess what i want to know from you is do I have my facts straight:)

I am looking at this again. I think I understand what you say maybe I had it backwards. On the test question I understood you disconnect the side that goes from the centrifugal switch to the heater side that goes up through the controls and get your power And left the other side to connected to L2 and got zero

I understand which ever side you get zero is where your problem is

I have something backwards. But I understand your response

This was the test question I worried about the most and it taken a while but I figured it out.

I finally had a chance to get back. So if I learned correctly this is what I have

Total 5005 ohms
Gives me a total 0.02398 current and 2.87712 power
I take 0.02398 x 0.02398 x 5 gives me 0.0028752
I take 0.02398 x 0.02398 x 5000 gives me 2.875202

I hope?

I don’t know what happened thank you. I’d have to reread the question, did I
Not add everything together? I know to do that, maybe I didn’t understand the question but I don’t know how that could be,

In the case of the first go round I didn’t read the question well with the first question. I thought the answer was voltage drop.

Anyway I’ll get too it. Thanks again for the help your always good help, and thanks for the reset

Thanks again

Maybe I should clarify.

I have 120 volts
I enter 5 ohms of resistance
I get current of 24 and power of 2880

This is not correct?

[desert]

Ill look at that again. But I did plug that info into an ohms law calculator And I get 2880 for power.

At any rate I did ask for a reset did you guys not get that?

[desert]

Thanks

I think I understand and I think it makes sense but I wanted to be sure is all.
