Question

According to Ohm's law what would happen to the current if resistance was increased?

Increase
Decrease
varys
nothing

Answer 1

This sounds a LOT...like a test question...mm? What is this for?

Answer 2

My friend is texting me asking me and I have no idea :P He helps me with math and normally science is my strong point XD. I think it would be physical science.

Answer 3

I = V/R, correct? Then what would happen to I if R was increased?

Answer 4

I think it would be for his physical science test or something* Didn't put that last bit in :P. I have no idea, I have never heard of this stuff before :P

Answer 5

R decrease as we keep V as a constant.. if im not mistaken

Answer 6

Well, if you can't make an assumption off of that, you're helpless. It's basic math. I = V/R. What happens to I if R increases. I don't want to just give you the answer, because that's cheating. It's not rocket science, man, and I can't trust if this is you asking the question or if it's your friend. Either way, use your head.

Answer 7

Since I=current, V=voltage, and R=resistance and from Ohm's law we can clearly see I=V/R then let's consider what we know about how fractions work.

As the numerator (top) increases, it makes a number bigger. Let's think about x/1. So if you say X=1, it's 1/1=1. X=2, it's 2/1=2. Makes sense?

As the denominator (bottom) increases, it makes a number smaller. 1/x, if we plug in 1 you get 1/1=1. For 2 you get 1/2 which is a half. It makes sense that as the bottom increases, the number gets smaller.

I hope that helps build some intuition on how fractions work so you understand and can think, alright, so for the fraction V/R does the fraction get bigger as the denominator increases for a constant numerator?

Answer 8

Well I told him everything you all said and I guess he got it right, so thanks for your help.
