For the first question, a better answer is: "Resistance in Parallel Circuits

AI Thread Summary
In a parallel circuit, if two legs carry similar amounts of current, their resistances are likely comparable due to the nature of parallel connections. The user correctly applies Ohm's Law to calculate current in a circuit with a 3V battery and 15Ω resistance, resulting in 0.2A. However, confusion arises from the rubric's mention of reversing Ohms and Volts, which may refer to the need to understand the relationship between voltage, current, and resistance. Utilizing conductance (G) can provide additional clarity, as G is the inverse of resistance. Overall, understanding these concepts is essential for accurate circuit analysis.

ok this is a simple question and i have the idea but just not 100% sure
If two legs of a parallel circuit have about the same about amount of current, what can you say about the resistance of each of these legs?

My answer is that both legs most probable have the same object, there resistance would be very alike

any corrections?

Another question was


Paul’s Super Marco video game uses batteries that produce 3 V. If the circuitry produces a resistance of 15 Ω, how much current is generated in the game?

I came up with
I=v/r
I=3/15
.2=3/15
.2 current generated in game
but...
on the rubric for the question it says
Reversing Ohms and Volts in formula (15/3)=10 points
im not quite sure what they mean by that any help would be great
Thanks!

Look at using conductance (G). G=1/R=I/V. Also, Wikipedia is a good place to find general information.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
