How Does Resistance Affect Current in Parallel Circuits?

[stickplot]

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(resistors), 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!

Your solution looks good.
Maybe the rubric means you would get or lose 10 points for writing 15/3 instead of 3/15.

It would be a very good habit to get into to write your solution this way:
I = V/R = 3/15 = 0.2
So easy to follow, you won't get mixed up and your marker will enjoy your work!

o ok thank you for your help. yeah i was confused about the rubric and what it meant thanks for the help.
