For 10 points, name this law which states that the voltage is equal to the product of current and resistance.
In tokamaks, a phenomenon named for this statement has a lower power density at high temperatures and will thus be used in complement with neutral beam injection and cyclotron resonance to perform heating in ITER. One version of this statement contains a term proportional to the cross product of the current density with the magnetic field. That term is known as the Hall current. Another version of this equation states that the (*) current density is equal to the product of the conductivity and the electric field. Combining this statement with another equation for the power yields Joule's Law. For AC circuits, one quantity in this statement is replaced with the impedance. For 10 points, name this law which states that the voltage is equal to the product of current and resistance.
