Even though the drift speedof electrons is very low, the bulb or any other appliance are switched on quickly because there are are billions of electrons per square area of the wire.
This large number of electrons contribute to a significant amount of energy enabling the appliance to be switched on immediately after the switch is pressed.

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?
