Question

Use ohm's law to solve: V=2, I=.5, Solve for R.
A: 2
B: 1.5
C: 4
D: 2.5

Answer 1

Ohm's law states that
v=i*r.

Answer 2

Do you get it now?

Answer 3

No -.-

Answer 4

Ok, no problem. Plugging in your values gives:
2= 0.5 * R.

Answer 5

Yea but what is R? -.-

Answer 6

Just solve for it using algebra. :)

Answer 7

If you want to know what it means in the formula, it means resistance.

Answer 8

okay so for. Use Ohm's law to solve: I=12, R=9, Solve for V. would it be 108?

Answer 9

v= 12 * 9 = 108. Good work!

Answer 10

Thanks haha and math is my best subject but with all this science stuff in here it throws me off :p

Answer 11

so Use ohm's law to solve: V=30, R=6, Solve for I ; is 5?

Answer 12

just want to make sure im right

Answer 13

Once you get the hang of physics, it really is mostly math.

Answer 14

Yes.
6*5=30.

Answer 15

Okay just wanted to make sure that i was doing the equation correctly

Answer 16

Thank you

Answer 17

You are very welcome!

Answer 18

@liamschumm What is the equation for this type or problem? A 12V battery runs a 30 amp car stereo. What is the resistance of the circuit?
