In hydrogen atom, the electron makes 6.6 x 10 to the power of 15 revolution per second around the nucleus in an orbit of radius 0.5 x 10 to the power of negative 10 end exponentm. Its equivelent current will be nearly
1. 1 A
2. 1mA
3. 1 microampere
3. 1.6 x 10 to the power of negative 19 end exponent A

begin mathsize 12px style We space know space that space straight I equals straight Q over straight t equals straight e over straight T But space straight T equals 1 over straight f rightwards double arrow straight I equals straight e cross times straight f space space space space equals 1.69 cross times 10 to the power of negative 19 end exponent cross times 6.6 cross times 10 to the power of 15 rightwards double arrow straight I equals 1.05 cross times 10 to the power of negative 3 end exponent straight A Or rightwards double arrow straight I equals 1 space mA end style

A semiconductor slab of thickness t=0.5 mm with length l=30 cm carrying current I=2A placed in a magnetic field B=0.25T directed into the page, perpendicular to the flat surface of the slab carries 7*10^24 electrons per m^3. Calculate the Hall voltage across the slab. Indicate which edge (top or bottom) is at higher potential and why?
