| Kirchhoff’s Voltage Law (KVL) and how important is it? |
| << < (3/3) |
| TimFox:
Ohm's law is independent of Maxwell's equations. It is just a linear approximation to the relationship between current density and electric field, which is quite accurate for solid conductors and not appropriate to semiconductor junctions or space-charge limited vacuum diodes. Objects that satisfy Ohm’s Law are called “ohmic”. |
