How Do You Calculate Hall Voltage Across a Ribbon?

[aesopsowner]

Hey there.
Trying to figure out how to find a hall voltage across a ribbon. I'm given J, B, and some other factor: R-sub-h OHM*meter/tesla. (no clue what this is... )I'm also told to assume the charge carriers are e-'s. I understand that the hall effect is used to determine which charges are actually moving, but i can't really understand how the hall voltage is determined outside of V(hall) = q*width of ribbon*B.

I'm really not looking for an answer, but some general guidelines or tools that will help me solve the problem. Thanks in advance.

Hi there! The Hall voltage is determined by the Hall effect, which states that when an electric current passes through a conductor in the presence of a magnetic field, a potential difference is created across the conductor. In other words, the Hall voltage is the ratio between the electric current and the magnetic field. As for the R-sub-h OHM*meter/tesla, this is the Hall coefficient, which is used to calculate the Hall voltage. To find the Hall voltage, you need to multiply the Hall coefficient by the current, the width of the ribbon, and the magnetic field strength. Hope this helps!
