Question

A 12.0 V voltage is applied to a wire with a resistance of 3.50 ohms. what is the magnetic field 0.150 m from the wire?
____x10^____T

Answer 1

Answer:

4.57x10^-6

Explanation:

So first you'll need to find the current, which is

I = voltage / resistance

which equals 3.43

Then just plug your numbers into the magnetic field equation to get your final answer

4.57x10^-6

Also it was right on Acellus lol

Hope this helps :)
